To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Current Condition: The coin has a condition of 30 (BC+), which indicates that it is not in the best condition. This will affect its value compared to coins in better condition.

2. Historical Prices: By looking at the auction prices of similar coins in the past, we can see that prices vary significantly depending on the condition. For example, coins with higher grades (such as 70, 80, 90, 95) have reached auction prices ranging from 8 euros to 190 euros.

3. Average Auction Price: The average auction price for this coin is 54.06 euros, which gives us an idea of what buyers are willing to pay on average.

4. Starting Price and Average Starting Price: The current starting price is 18 euros, and the average starting price is 34.08 euros. This suggests that the starting price is relatively low compared to the average auction price.

5. Sales Trends: The coin has been auctioned 38 times, of which it has sold 32 times. This indicates a consistent interest in the coin, which may influence its price.

Given all this, and considering that the coin's condition is 30 (BC+), an estimated maximum purchase price could be in the range of 30 to 50 euros. This is based on the fact that, although the condition is not high, the interest in the coin and historical prices suggest it could reach a reasonable price at auction.

Therefore, an estimated maximum purchase price could be 40 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 18.07 euros.
- The coin has been auctioned 20 times, of which it has sold 14 times, indicating good demand.

- The current starting price is 9 euros, and the average starting price is 9.53 euros. This suggests that the starting price is reasonable compared to the history.
- The estimated price for this auction is 20 euros, which is also a good indicator.

4. Price Trends:
- In recent auctions, the hammer price has been around 10-20 euros for coins of similar condition.

Based on these factors, an estimated maximum purchase price could be between 20 and 30 euros, considering that the condition is high and there is a price history that supports this estimate. Therefore, a reasonable maximum purchase price could be 25 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 85 (ebc-), indicating that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for similar coins has been 42.55 euros.
- In previous auctions, coins with a similar condition (85) have had hammer prices that vary, but some examples are:
- 40 euros (2020-11-10)
- 30 euros (2020-11-03)
- 36 euros (2017-07-05)
- 50 euros (2017-09-21)
- The trend shows that the hammer price can be in a range of 30 to 50 euros for similar conditions.

3. Starting Price and Average Starting Price:
- The starting price is 15 euros, and the average starting price is 30.64 euros. This suggests that the hammer price could be significantly higher than the starting price.

4. Recent Trends:
- Recent auctions have shown increasing interest, with hammer prices sometimes exceeding 50 euros for coins in similar conditions.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 45 to 60 euros. This is based on the historical hammer prices for coins of similar condition and the trend of prices in recent auctions.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition of 75 (MBC), which indicates that it is in fairly good shape, but not of the highest quality (FDC).

2. Historical Prices: By looking at previous auction prices for coins with a similar condition (around 75), we can see that auction prices have varied. For example, in recent auctions, coins with a condition of 75 have reached hammer prices of up to 70-80 euros.

3. Average Hammer Price: The average hammer price for this coin is 75.57 euros, which gives us a good reference for what buyers are willing to pay.

4. Starting Price and Average Starting Price: The starting price is 15 euros, and the average starting price is 53.19 euros. This suggests that there is a considerable margin between the starting price and the hammer price.

5. Recent Trends: The coin has been auctioned 205 times in the past, with an 85% sell-through rate, indicating consistent demand.

Based on these factors, an estimated maximum purchase price for this coin could be between 80 and 100 euros, considering that the condition is good and that there is a trend for hammer prices to remain in that range for coins of similar condition.

Therefore, a reasonable maximum purchase price could be 90 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition of 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price for similar coins has been 115.67 euros.
- In previous auctions, coins with similar conditions (around 70) have had hammer prices that varied, but some examples are:
- 55 euros (condition 75)
- 52 euros (condition 80)
- 90 euros (condition 80)
- 130 euros (condition 80)
- The trend shows that coins with conditions from 70 to 80 can reach hammer prices between 50 and 130 euros.

3. Starting Price: The starting price is 18 euros, indicating that the seller expects a lower price initially, but this does not necessarily reflect the actual value of the coin.

4. Previous Prices: In previous auctions, the highest hammer price for coins with similar conditions has been 190 euros (condition 95), but this is an exceptional case.

Based on these factors, an estimated maximum purchase price for the coin with a condition of 70 could be in the range of 80 to 120 euros, considering that the average hammer price is 115.67 euros and that the condition is slightly lower than that of coins that have reached higher prices.

Therefore, a reasonable estimated maximum purchase price could be 100 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The coin has been auctioned 7 times and has sold on all occasions, suggesting consistent demand.
- The average hammer price in previous auctions is 43 euros, which can serve as a good indicator of market value.

3. Previous Prices:
- Previous hammer prices for coins with similar conditions (80) have been 31 and 30 euros, indicating that the price may vary depending on the condition.
- In the case of the 2014 auction, the hammer price was 130 euros, but this may have been influenced by a higher condition or other market factors at that time.

4. Starting Price and Average Starting Price:
- The current starting price is 18 euros, which is quite low compared to the average hammer price of 43 euros. This suggests that there is potential for the hammer price to be significantly higher.

Based on these factors, an estimated maximum purchase price could be in the range of 50 to 70 euros, considering that the condition is good and that the price history suggests there is demand. However, since the starting price is low, there may be an opportunity for the hammer price to be even higher if there is interest among bidders.

Therefore, a reasonable maximum purchase price could be 65 euros.

To estimate a maximum purchase price for the coin that will be auctioned, let's consider several factors:

1. Condition: The coin has a condition of 100 (MS), indicating that it is in excellent shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction history:
- The average hammer price for coins of similar condition (100) has been 27 euros.
- In previous auctions, the highest hammer price for a coin with a condition of 100 was 30 euros.

3. Starting price: The starting price is 18 euros, which is relatively low compared to previous hammer prices.

4. Sales trends: The coin has been sold in 48 out of 63 auctions, indicating good demand.

5. Previous estimated prices: In past auctions, the estimated price for coins in condition 100 has been up to 30 euros.

Taking all these factors into account, a reasonable estimated maximum purchase price could be between 30 and 35 euros, given that the condition is excellent and there is a history of hammer prices supporting this figure. However, since the starting price is 18 euros, some bidders may try to acquire it for a lower price, which could influence the final outcome of the auction.

Therefore, a reasonable maximum purchase price could be 30 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Condition: The coin has a condition rating of 95 (S/C-), indicating that it is in very good shape. This generally increases its value compared to coins with lower conditions.

2. Auction history:
- The average hammer price in previous auctions is 20.4 euros.
- The last auction with a known hammer price was 30 euros for a coin with a condition of 100, suggesting that coins in better condition can reach higher prices.
- In previous auctions, hammer prices have varied, but there are examples of similar coins that have reached prices of 25 euros or more.

3. Starting price and estimated prices:
- The current starting price is 9 euros, which is relatively low compared to the average hammer price.
- The estimated price for this auction is 20 euros, which also aligns with previous hammer prices.

Taking these factors into account, an estimated maximum purchase price could be in the range of 25 to 30 euros, given that the condition is high and the price history suggests that coins in similar conditions have reached those values.

Therefore, a reasonable maximum purchase price could be 30 euros.
