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

1. Current Condition: The coin has a condition rating of 90 (EF), indicating that it is in quite good shape.

2. Historical Prices: By looking at previous auction prices for coins with similar conditions, we can see that auction prices have varied. For example, in recent auctions, coins with condition ratings of 90 have reached hammer prices of up to 400 euros.

3. Starting Price and Average Hammer Price: The current starting price is 325 euros, and the average hammer price in the past has been 283.35 euros. This suggests that the starting price is reasonable and could attract bidders.

4. Recent Trends: In the most recent auctions, hammer prices have shown an upward trend, with some reaching up to 450 euros for similar conditions.

Based on these factors, an estimated maximum purchase price for this coin could be between 400 and 450 euros, considering that interest in well-preserved coins may lead to competition among bidders. Therefore, a reasonable maximum purchase price could be approximately 450 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 95 (EF+), which indicates that it is in very good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Previous Prices: By observing previous auction prices for coins with similar conditions (95 and 90), we can see that auction prices have varied but have reached significant figures. For example, in recent auctions, coins with a condition of 95 have reached hammer prices of up to 440 euros.

3. Starting Price and Average Hammer Price: The current starting price is 375 euros, and the average hammer price in the past has been 284.7 euros. However, given that the condition of this coin is high, it is reasonable to expect that the hammer price will be above the average.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 360 to 440 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 400 to 450 euros. This reflects both the high condition of the coin and the price trends in recent auctions.

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

1. Condition of the coin: The coin to be auctioned has a condition rating of 95 (EBC+), indicating that it is in very good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous auction prices: By looking at the hammer prices of coins with similar conditions (around 95), we can see that the hammer prices have varied, but there are recent examples showing hammer prices of up to 440 euros.

3. Starting price and average hammer price: The starting price is 375 euros, and the average hammer price in previous auctions is 297.25 euros. However, given that the condition of this coin is high, it is reasonable to expect that the hammer price will be above the average.

4. Recent trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 400 to 450 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 440 and 480 euros, considering that collector interest and the quality of the coin may lead to a higher hammer price. Therefore, a reasonable maximum purchase price could be 450 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 75 (MBC), indicating that it is in an acceptable state, but not of the highest quality.

2. Auction History:
- The average hammer price for similar coins has been 556.76 euros.
- In previous auctions, coins with similar conditions (75) have had hammer prices that varied, but some examples are:
- 2019-09-19: 280 euros (condition 75)
- 2020-07-08: 225 euros (condition 75)
- 2023-01-31: 340 euros (condition 75)
- The highest recorded price for a coin in similar condition was 650 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 300 euros, which is below the average starting price of 393.06 euros.

4. Recent Trends:
- In the most recent auctions, hammer prices have shown a trend of being in the range of 300 to 600 euros for similar conditions.

Based on this data, an estimated maximum purchase price for the coin could be in the range of 500 to 650 euros, considering that the condition is acceptable and that the price history shows that similar coins have reached those values.

Therefore, a reasonable maximum purchase price could be 600 euros.

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

1. Starting price: 500 euros.
2. Average starting price: 1050 euros.
3. Average hammer price: 2575.68 euros.
4. Auction history:
- In 2011, it was sold for 3800 euros.
- In 2012, with a condition of 75, it was sold for 2800 euros.
- In 2021, also with a condition of 75, it was sold for 3062.73 euros.
- In 2022, it was estimated at 2953.47 euros with a condition of 75.

Since there is no information about the condition of the current coin, it is difficult to make a direct comparison. However, we can observe that coins with a condition of 75 have reached hammer prices between 2800 and 3062.73 euros.

If we consider that the current coin might have a similar or better condition, we could estimate a maximum purchase price based on previous hammer prices.

A reasonable approach would be to take the average hammer price of coins with a condition of 75, which is approximately 2885.36 euros (average of 2800, 3062.73, and 2953.47).

Given that the starting price is 500 euros, and considering that the market may be willing to pay a higher price, a maximum purchase price could be around 2885 euros, although it might be wise to adjust this figure downward to account for uncertainty regarding the condition.

Estimated maximum purchase price: 2800 - 3000 euros.

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

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

2. Previous Prices:
- In 2013, a coin with a condition of 90 sold for 11,254.63 euros.
- In 2014, a coin with a condition of 50 sold for 4,100 euros.
- In 2021, another coin with a condition of 90 sold for 6,952.57 euros.

3. Average Hammer Price: The average hammer price for this reference is 5,951.80 euros, which gives us an idea of the market value.

4. Current Starting Price: The current starting price is 900 euros, which is significantly lower than the previous hammer prices.

Given that the condition of the coin is 75, which is better than 50 but lower than 90, we can estimate that its value should be between the hammer prices of coins with conditions of 50 and 90.

We can make an approximate calculation considering that the price of a coin with a condition of 75 could be in an intermediate range. One approach could be to take a weighted average of the previous hammer prices, adjusting for condition:

- Hammer price for condition 90: 11,254.63 and 6,952.57 (average: 9,103.60)
- Hammer price for condition 50: 4,100

We can estimate that a coin with a condition of 75 could have an approximate value of:

\[
\text{Estimated Price} = \frac{(9,103.60 + 4,100)}{2} \approx 6,601.80
\]

However, since the average hammer price is 5,951.80 euros, and considering that the condition is not the best, a reasonable maximum purchase price could be slightly lower than this average.

Therefore, an estimated maximum purchase price for this coin could be around 6,000 to 7,000 euros.
