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

1. Conservación Actual: La moneda tiene una conservación de 85 (ebc-), lo que indica que está en un estado bastante bueno. Esto generalmente se traduce en un precio más alto en comparación con monedas de menor conservación.

2. Historial de Subastas:
- El precio medio de remate de monedas similares en el pasado es de 72.28 euros.
- La última subasta de esta moneda tuvo un precio de remate de 91 euros, lo que sugiere que hay un interés creciente en esta moneda.
- La subasta más alta registrada para esta moneda fue de 170 euros en 2018, aunque la conservación de esa moneda era de 90.

3. Precio de Salida y Estimaciones:
- El precio de salida actual es de 70 euros, que es un buen punto de partida.
- El precio estimado para esta subasta es de 90 euros, lo que indica que se espera que alcance un precio más alto.

4. Tendencias de Venta: La moneda ha sido vendida en 18 de las 19 subastas anteriores, lo que indica que hay una demanda constante.

Con base en estos factores, un precio estimado máximo de compra podría situarse entre 90 y 120 euros. Dado que la conservación es buena y hay un interés creciente, un precio máximo de compra razonable podría ser de 100 euros. Esto permite un margen para competir en la subasta sin sobrepasar el valor histórico de la moneda.

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 80 (MBC+). This is an important factor, as coins in better condition tend to reach higher prices.

2. Previous Auction Prices: By observing previous auction prices for coins with similar conditions (around 80-85), we can see that they have reached auction prices that vary considerably, but some examples are:
- 320 euros in 2018 (condition 85)
- 290 euros in 2022 (condition 85)
- 270 euros in 2023 (condition 85)
- 210 euros in 2022 (condition 80)

3. Average Auction Price: The average auction price for this coin is 164.67 euros, which gives us an idea of what buyers are willing to pay on average.

4. Starting Price and Estimates: The starting price is 90 euros, and the average starting price is 89.41 euros. This suggests that the starting price is reasonable compared to the auction history.

5. Sales Trends: The coin has been auctioned 17 times, of which 15 have been sold. This indicates good demand and consistent interest in the coin.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that the condition is slightly lower than the coins that have reached higher prices, but there is still an auction history that suggests it could reach a significant price.

Therefore, an estimated maximum purchase price could be 250 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 rating of 80 (MBC+), which indicates that it is in relatively good shape, but not of the highest quality (FDC).

2. Auction History:
- The average hammer price for similar coins has been 382.25 euros.
- In previous auctions, we have seen hammer prices that varied significantly, ranging from 60 euros to over 2000 euros, depending on the condition and demand at that time.
- The last auction of a similar coin with a condition rating of 80 had a hammer price of 380 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 100 euros, which is quite low compared to the average hammer price.
- The average starting price for similar coins is 180.55 euros.

4. Recent Trends:
- In the most recent auctions, hammer prices for coins with a similar condition have been in the range of 100 to 380 euros.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 300 to 400 euros, considering that the average hammer price has been 382.25 euros and that the condition is good, but not excellent.

Therefore, a reasonable maximum purchase price could be 400 euros.

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

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- In the past, the coin has been auctioned 5 times, and all have sold, indicating consistent demand.
- Previous hammer prices have varied, but the highest was 92.24 euros in 2015 with a condition of 75, and 90 euros in 2020 with a condition of 80.

3. Current Starting Price: The starting price is 120 euros, which is significantly higher than previous hammer prices. This may indicate that the seller expects an increase in value, possibly due to the condition or current demand.

4. Average Hammer Price: The average hammer price of 70.25 euros suggests that, in general, coins of this reference have sold for a price lower than the current starting price.

5. Market Trends: Given that the condition of the coin is better than some of the previous auctions, it is reasonable to assume that it could reach a higher price than previous hammer prices, but not necessarily the starting price.

Taking all these factors into account, an estimated maximum purchase price could be between 90 and 100 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, given the starting price of 120 euros, it is possible that some bidders may be willing to pay a bit more, but it would be wise not to exceed 100 euros to ensure a reasonable purchase.

1. Grade: The grade of the coin in question is 80 (MS+). In the past, coins with a similar grade have had hammer prices that vary considerably, but they are generally found in a higher range than the current starting price.

2. Previous hammer prices: By observing the hammer prices of coins with a grade of 80, we find that they have reached hammer prices of up to 170 euros (as in the auction on December 11, 2019). However, there are also examples of lower prices, such as 55 euros in recent auctions.

3. Average hammer price: The average hammer price for this particular coin is 111.05 euros, indicating that, in general, coins of this reference tend to sell for above their starting price.

4. Recent trends: In the most recent auctions, hammer prices have shown some variability, but the starting price of 70 euros is relatively low compared to previous hammer prices.

5. Sales expectations: Given that there are 2 auctions scheduled in the coming days, this may influence demand and, therefore, the hammer price.

Based on these factors, an estimated maximum purchase price for the coin with a grade of 80 (MS+) could be in the range of 120 to 150 euros. This is based on the analysis of previous hammer prices and the average hammer price, taking into account that interest in the coin may vary depending on demand at the auction.

5. Recent Trends: In the most recent auctions, hammer prices have been higher, which could indicate an increase in demand.

Based on these factors, an estimated maximum purchase price could be in the range of 140 to 160 euros, considering that the coin has a starting price of 120 euros and that there have been recent sales in the upper range. However, since the condition is 70, it is wise not to exceed this range too much to avoid overpaying.

Therefore, a reasonable maximum purchase price could be 150 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-). This indicates that it is in an acceptable state, but not among the best qualities.

Based on these factors, an estimated maximum purchase price for this coin could be between 150 and 180 euros, considering that the condition is a limiting factor and that the starting price is 130 euros. This allows for some margin for competition in the auction, but also reflects the historical interest and demand for the coin.

Therefore, a reasonable maximum purchase price could be 170 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 80 (MS+), indicating that it is in quite good shape. This is important because coins in better condition tend to fetch higher prices.

4. Recent Trends: In the most recent auctions, hammer prices have shown a range that can be higher, especially for coins in good condition. For example, in the March 2023 auction, a coin with a condition of 95 sold for 480 euros, indicating that there is an active market willing to pay more for quality coins.

5. Comparison with Previous Prices: Looking at the hammer prices of coins with a condition of 80, the range seems to be between 100 and 150 euros, with some exceptional cases.
