The G 1 $1 Gold coin, also known as the Liberty Head design, was minted in the United States from 1849 to 1889. The 1878 Philadelphia mint issue is part of this series and is primarily composed of 90% gold and 10% copper. These coins, also referred to as "Type I" coins from the Liberty Head series, are notable for their small size and are popular among collectors for their historical significance and gold content. The Philadelphia mint struck millions of these coins, making them relatively accessible in various grades but still collectible depending on rarity and condition.
