1914-D Lincoln Wheat Cent
According to Gainesville Coins, the 1914-D Lincoln Wheat cent had a very low mintage in its series for its year. The rarity of this coin makes it worth at least $175 to collectors.
1916-D Mercury Dime
Also known as the Winged Liberty Head dime, this model, which was minted in 1916, is as beautiful as it is rare. Gainesville Coins shared that there were only 264,000 coins minted, which means collectors are especially glad to see this coin that bears the visage of the Roman god Mercury in front of them. These coins can go for around $800. Precious metals dealer Apmex is currently selling one in almost good condition for $832.
1921 Peace Dollar
Gainesville Coins called the Peace Dollar a “beloved” model, and it’s not hard to see why with its elegant and inspiring design. The coins from the 1921 mintage were created with a high relief design that was beautiful to look at but not exactly conducive for everyday use, requiring the relief to be lowered. Gainesville Coins priced them at $125 at least. Rare Collectibles TV is selling one for nearly $240.
Pre-1933 U.S. Gold Coins
Did you know that before 1933, gold coins were minted as everyday money? They were, and Gainesville Coins shared that these coins are 90% pure gold. They’re popular with coin collectors and gold investors alike. According to Gainesville Coins, these can go for at least $150.
