A complete proof set of five gold coins (20 dollar, half-eagle, quarter eagle, one dollar and a half dollar) can typically be worth more than $100,000 due to their great rarity. Each coin of good grade might be worth $15,000 and up, and the set in full is more than the individual prices.
Uncirculated Set:
A complete set of five uncirculated gold coins with no blemishes or surface problems might sell for close to $10,000, with individual prices of more than $2,000. The quarter eagle and half eagle are the most popular.
Circulated Set:
A five-coin set of circulated coins from 1934 (with the one dollar omitted as it was not coined in this specific year) would likely be worth more than $5,000. Individual prices for the remaining gold coins may range from $500 and $1,000.
*However, it's crucial to keep in mind that the coin's grade and condition can significantly affect its value, so it's advisable to have it professionally evaluated by a numismatist for a more accurate estimate. The values mentioned above are approximate and can vary based on market conditions.*
