1. Current Condition: The coin has a condition rating of 80 (MS+). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Previous Prices: By looking at previous auction prices for coins with similar conditions (around 80), we can see that they have reached auction prices that vary, but some examples are:
- 2019-09-19: Auction price 15 (condition 80)
- 2018-07-04: Auction price 28 (condition 80)
- 2022-11-16: Auction price not available, but starting price 15 (condition 80)

3. Average Auction Price: The average auction price for this coin is 101.18 euros, indicating that, in general, coins of this reference tend to sell for higher prices.

4. Starting Price: The starting price is 15 euros, suggesting that the auctioneer expects minimal interest in the coin.

5. Recent Trends: In the most recent auctions, the auction prices have varied, but there are examples of similar coins that have reached auction prices of up to 240 euros (2023-03-16, condition 100).

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 60 to 100 euros, considering that the condition is good (80) and there is a history of auction prices suggesting it could reach higher prices in competitive auctions.

Therefore, a reasonable estimated maximum purchase price could be 80 euros.

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

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. In the past, coins with a similar condition have had auction prices that vary.

2. Auction History:
- In the past, coins with a condition of 70 have been auctioned, and the final prices have been quite variable. For example:
- In 2020, a coin with a condition of 70 was sold for 8 euros.
- In 2018, another coin with the same condition did not sell, but it had a starting price of 12 euros.
- There are also examples of coins with higher conditions (such as 90 or 95) that have sold for significantly higher prices (up to 120 euros).

3. Starting Price and Average Price:
- The current starting price is 12 euros, and the average final price in the past has been 55 euros. This suggests that there is potential for an increase in the final price.

4. Recent Trends:
- In the most recent auctions, final prices have been lower for similar conditions (for example, 20 euros for a condition of 80).

Based on these factors, an estimated maximum purchase price could be between 20 and 30 euros. This is based on the auction price history for coins with similar conditions and the average final price observed.

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

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

1. Current Condition: The coin is in a condition of 90 (EF), which indicates that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Current Starting Price and Previous Prices: The current starting price is 170 euros, and the average hammer price in previous auctions is 266.59 euros. This suggests that the coin has a market value that could be considerably higher than the starting price.

3. Auction History: In the past, the coin has had hammer prices that varied significantly, from 25 euros to 1400 euros, depending on the condition and demand at that time. However, the higher prices have been seen in coins with similar or better conditions.

4. Recent Trends: Looking at the most recent auctions, there is an increase in hammer prices, which could indicate a rising trend in interest for this coin.

5. Price Estimates: Based on the average hammer price of 266.59 euros and considering that the condition of the coin is good, an estimated maximum purchase price could be in the range of 300 to 400 euros, depending on the competition in the auction and the interest from other bidders.

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 25 (BC), indicating that it is not in very good shape. This will negatively affect its value compared to coins in better condition.

2. Auction History:
- The average starting price for similar coins is 135.53 euros, and the average hammer price is 306.31 euros.
- In the past, coins with a condition rating of 70 have reached hammer prices of up to 950 euros. However, these coins are in much better condition than the one we are evaluating.

3. Sales Trends:
- Out of the 58 times this coin has been auctioned, it has sold on 46 occasions, indicating good demand.
- The current starting price is 20 euros, which is relatively low compared to the average starting price of other auctions.

4. Previous Prices:
- The hammer prices for coins with similar conditions (BC) have been significantly lower. For example, in previous auctions, hammer prices for coins in similar conditions have ranged from 20 to 70 euros.

Given all this, and considering that the coin's condition is a critical factor limiting its value, an estimated maximum purchase price could be in the range of 30 to 50 euros. This is based on the fact that, although there is a history of higher prices for coins in better condition, the current condition of this coin limits its appeal to collectors.

Therefore, a reasonable maximum purchase price could be 40 euros.
