The Saint-Gaudens Double Eagle from 1933 is considered to be the most valuable coin in the world of coin collecting, since it has been sold at auction for more than $18 million.
Collectors seek for this coin not just for its aesthetic value but also for the fact that it depicts a young America. As a result, it is an essential component of any collection that is considered to be noteworthy.
Despite the fact that it did not surpass the $10 million threshold, the 1913 Liberty Head Nickel is worthy of being mentioned due to its unique history and outstanding value.
Struck under strange circumstances, the Liberty Head design was intended to be replaced by the Buffalo Nickel in 1913. Their rarity and the mysteries surrounding their production have boosted their value to over $4.5 million for a single piece.
In addition to its historical importance and the fact that it was produced before the United States Mint was established, it is an extremely valuable coin, as shown by the fact that specimens of it have been sold at auction for more than $7.4 million.
