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 85 (ebc-), which indicates that it is in quite 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 28.6 euros.
- The coin has been auctioned 16 times, of which it has sold 11 times, indicating good demand.
- In previous auctions, the hammer price has varied, but there are examples of sales that have reached up to 110 euros under similar conditions.

3. Starting Price: The current starting price is 30 euros, which is a good starting point.

4. Price Trends: Observing previous hammer prices, it seems there is a price range that varies depending on the condition and demand at the time of the auction.

Given that the condition of this coin is quite good and considering the price history, an estimated maximum purchase price could be in the range of 50 to 70 euros. This is based on the fact that, although the starting price is 30 euros, the condition and demand could lead to a higher hammer price.

Therefore, an estimated maximum purchase price could be 70 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 (EF+), 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 for this coin has been 17.29 euros.
- In previous auctions, coins with a similar condition (95) have reached hammer prices that vary, but some recent examples show hammer prices of up to 40 euros (as seen in the December 2021 auction).

3. Starting price and estimates:
- The current starting price is 9 euros, and the average starting price in the past has been 11.24 euros.
- The estimated price for this auction is 15 euros, suggesting that bidders are willing to pay more than the starting price.

4. Sales trends: Of the 52 times it has been auctioned, it has sold on 24 occasions, indicating a consistent interest in the coin.

Based on these factors, a reasonable maximum purchase price could be in the range of 25 to 35 euros, considering that the condition is high and there is a history of hammer prices that supports this estimate. However, given the interest and demand, it may be wise to be prepared to bid up to 40 euros if competition is strong.

Therefore, an estimated maximum purchase price could be 35 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.

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 analyze several factors:

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

4. Supply and demand: The coin has been auctioned 38 times, of which it has sold 27 times. This indicates good demand, which can influence the price.

Based on these factors, an estimated maximum purchase price for this coin could be around 200 euros. This is based on the auction price history and the excellent condition of the coin. However, it is important to consider that the final price may vary depending on competition in the auction and other market factors at the time of sale.

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

2. Auction History:

4. Sales Trends: Of the 32 times it has been auctioned, it has sold 19 times, indicating a reasonable sales rate.

Based on these factors, an estimated maximum purchase price could be in the range of 80 to 120 euros, considering that the condition is good and that the hammer price history suggests it could reach higher figures in auctions. However, since the starting price is low, it could be a good opportunity to acquire it at a more accessible price.

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

4. Recent Trends: In the most recent auction, a coin with a condition of 100 sold for 950 euros, indicating that there is a strong market for high-quality coins.

Based on these factors, an estimated maximum purchase price for the coin in condition 90 could be between 200 and 300 euros, considering that the average hammer price is 151.54 euros and there is potential for an increase due to the good condition and market demand.

To estimate a maximum purchase price for the coin with a grade of 95 (EF+), we can analyze historical data from previous auctions and hammer prices.

1. Current coin data:
- Grade: 95 (EF+)
- Starting price: €18
- Average hammer price: €44.08

- Considering that the highest hammer price in the past for coins of similar grade has been €180, and that the average hammer price is €44.08, we can estimate a price range.

4. Maximum price estimation:
- Given that the coin's grade is high (95), a hammer price that could be considered reasonable might be in the range of €150 to €200.
- To be conservative, an estimated maximum purchase price could be €150.

Therefore, the estimated maximum purchase price for the coin with a grade of 95 (EF+) could be €150.
