To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially considering the current grade of the coin (30 BC+) and the auction prices of coins with similar grades in the past.

1. Current Grade: The coin has a grade of 30 (BC+), indicating that it is not in the best condition. This generally translates to a lower auction price compared to coins in better condition.

2. Historical Auction Prices: By observing the auction prices of coins with similar grades (around 30), we find that:
- In previous auctions, coins with a grade of 30 have reached auction prices between 15 and 30 euros.
- For example, in the auction on 2018-12-11, a coin with a grade of 30 was sold for 15 euros.

3. Price Trends: The average auction price for this particular coin is 107.29 euros, but this includes coins in better condition. Given that the current grade is quite low, it is unlikely that this price will be reached.

4. Starting Price and Estimates: The starting price is 12 euros, and the average starting price in the past has been 54.55 euros. However, since the grade is low, it is reasonable to adjust expectations towards a lower auction price.

5. Final Estimate: Taking all these factors into account, a maximum estimated purchase price for this coin, considering its grade and historical auction prices, could be between 20 and 30 euros. This reflects a balance between the current grade and the auction prices of similar coins in the past.

Therefore, a maximum estimated purchase price for this coin 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 has a condition of 30 (BC+). This indicates that it is not in the best condition, which generally affects its value.

2. Auction History: By observing the hammer prices of coins with a similar condition (30) in the past, we can see that the hammer prices have varied. For example:
- In previous auctions, coins with a condition of 30 have reached hammer prices ranging from 10 to 20 euros.
- The average hammer price for coins with higher conditions (such as 70 or 80) has been significantly higher, but this cannot be directly applied to a coin with a condition of 30.

3. Starting Price and Average Hammer Price: The current starting price is 12 euros, and the average hammer price for similar coins is 98.74 euros, but this includes coins in better condition.

4. Recent Trends: In the most recent auctions, the hammer prices for coins with a condition of 30 have been in the range of 15 to 30 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 20 and 25 euros. This is based on the analysis of past auctions and the current condition of the coin.

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

1. Coin Condition: The coin has a condition of 70 (MS-), which indicates that it is in acceptable shape, but not of high quality. This generally affects the price, as coins in better condition tend to fetch higher prices.

2. Auction History: By observing the hammer prices of coins with a similar condition (70) in the past, we can see that they have reached varying hammer prices. For example, in previous auctions, coins with a condition of 70 have had hammer prices ranging between 20 and 30 euros.

3. Average Hammer Price: The average hammer price for this particular coin is 98.74 euros, but this includes coins of different conditions. Given that the condition of this coin is 70, it is likely that the actual hammer price will be below this average.

4. Starting Price and Previous Prices: The current starting price is 15 euros, and the average starting price in the past has been 65.9 euros. However, the hammer prices of similar coins have been lower, suggesting that the starting price may be a good indicator of what to expect.

5. Recent Trends: In the most recent auctions, the hammer prices for coins with similar conditions have been in the range of 20 to 30 euros.

Based on these factors, an estimated maximum purchase price for this coin could be between 25 and 35 euros. This reflects a balance between the condition of the coin and the historical hammer prices for similar coins.

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. Condition of the coin: The coin has a condition rating 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 they have varied. For example:
- In previous auctions, coins with a condition of 70 have reached hammer prices of 20, 30, and even 50 euros.
- The average hammer price for coins of similar condition seems to be in the range of 20 to 50 euros.

3. Average hammer price: The average hammer price for this particular coin is 98.74 euros, but this may be influenced by coins of better condition or exceptional auctions.

4. Starting price: The starting price is 15 euros, which suggests that the auctioneer expects moderate interest in the coin.

5. Auction trends: Given that the coin has been auctioned 218 times in the past, and has had a considerable number of sales (182), this indicates that there is an active market for this coin.

### Estimation of the maximum purchase price:
Taking all these factors into account, a reasonable maximum purchase price for this coin, considering its condition and previous hammer prices, could be between 40 and 60 euros. This is based on the fact that, although the average hammer price is higher, the condition of the coin limits its value compared to coins of better quality.

Therefore, an estimated maximum purchase price could be 50 euros.

Para estimar un precio máximo de compra para la moneda en cuestión, consideraremos varios factores:

1. Conservación Actual: La moneda tiene una conservación de 80 (MBC+). Esto es un factor importante, ya que las monedas en mejor estado suelen alcanzar precios más altos.

2. Precio de Salida y Precio Medio de Remate: El precio de salida es de 325 euros, y el precio medio de remate en subastas anteriores es de 299.08 euros. Esto sugiere que el precio de remate suele estar cerca del precio de salida.
