To estimate a maximum purchase price for the coin in question, we can analyze the provided data:

1. Current condition: The coin has a condition of 80 (MBC+), which indicates that it is in fairly good shape, although it is not the best possible condition.

2. Previous prices:
- In 2011, a coin with a condition of 90 sold for 170 euros and 115 euros at different auctions.
- In 2014, another coin with unspecified condition (but likely similar) sold for 130 euros.

3. Average hammer price: The average hammer price for this coin is 120 euros, suggesting that, in general, coins of this reference tend to sell around this price.

4. Starting price: The starting price is 60 euros, which may attract more bidders, but does not necessarily indicate the final hammer price.

Given that the condition of the coin is 80 (MBC+), which is lower than the conditions of 90 that have sold in the past, it is reasonable to adjust the estimated price downward compared to previous hammer prices.

Taking all these factors into account, an estimated maximum purchase price could be around 100-110 euros. This is based on the fact that, although the condition is good, it is not the best, and the average hammer price suggests that there could be competition, but not at the level of the higher conditions.

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 80 (MS+), indicating that it is in relatively good shape. This suggests that its value could be in the upper range of coins with similar conditions.

2. Auction History:
- The average hammer price for coins with similar conditions (80) has been 65 euros in a previous auction (2022-06-01).
- In other auctions with a condition of 80, hammer prices have varied, but they have generally remained in a range of 15 to 80 euros.

3. Starting Price and Average Hammer Price:
- The current starting price is 15 euros, which is quite low compared to the average hammer price of 48.8 euros.
- The average starting price of 32.27 euros also suggests that there is potential for an increase in the hammer price.

4. Sales Trends: The coin has been sold on all previous occasions, indicating consistent demand.

Based on these factors, an estimated maximum purchase price could be in the range of 60 to 80 euros, given that the condition is good and the hammer price history for similar coins supports this estimate.

Therefore, a reasonable maximum purchase price could be 70 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the current condition of the coin.

1. Current Condition: The coin has a condition of 70 (VF-). This indicates that it is in an acceptable state, but not of high quality.

2. Previous Auction Prices: By looking at the auction prices of coins with a similar condition (70), we can see that the auction prices have varied. Some examples are:
- 50 euros (2020-12-14)
- 51 euros (2019-12-10)
- 60 euros (2023-05-23)
- 75 euros (2022-10-18)

3. Average Auction Price: The average auction price for this coin is 101.29 euros, but this includes coins of different conditions. For a condition of 70, it is likely that the auction price will be lower.

4. Price Trends: The current starting price is 30 euros, which suggests that the seller expects a lower auction price than the average. However, the average starting price is 61.44 euros, indicating that in the past, similar coins have had a higher starting price.

5. Estimation: Given that the condition is 70 and considering the previous auction prices, an estimated maximum purchase price could be between 50 and 75 euros. This is based on the previous auction prices for coins with a similar condition.

Therefore, an estimated maximum purchase price for this coin could be 70 euros.

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 70 (VF-), which indicates that it is in relatively good shape, but not of the highest quality (UNC).

2. Auction History:
- The average hammer price in previous auctions is 84.11 euros.

3. Starting Price and Estimates:
- The current starting price is 40 euros, which is relatively low compared to the average hammer price.
- The estimated price for this auction is 90 euros, suggesting expectations for it to sell at a higher price.

4. Price Trends:
- In previous auctions, hammer prices have varied, but there are examples of coins with similar conditions that have sold for significantly higher prices (up to 200 euros).

Based on these factors, an estimated maximum purchase price could be in the range of 80 to 100 euros. This is because, although the condition is not the highest, demand and price history suggest it could reach a higher price at auction.

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 rating of 75 (MBC), indicating a medium-good quality. This generally translates to a higher price compared to coins with lower conditions.

3. Starting Price and Average Starting Price: The current starting price is 60 euros, and the average starting price in the past has been 50.63 euros. This suggests that the current starting price is reasonable and could attract buyers.

4. Price Trends: Observing the trends, it seems that coins with a condition of 75 can reach hammer prices ranging from 100 to 150 euros, depending on demand and other market factors.

Based on these points, an estimated maximum purchase price for this coin could be between 100 and 130 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 130 euros.
