2020 American Silver Eagle Obverse Struck Thru Mint Error NGC MS69
First produced by the US Mint in 1986 and contains 1oz of .999 Fine Silver.
Fully authenticated by NGC as a Mint Error Obverse Struck Thru in MS69 in the new Eagle Core Holder. The Strike Thru is located to the left of "In God We Trust."
A strike through error is when some sort of foreign object or substance on either the die, or the planchet (coin blank), somehow got between them during the striking of the coin, and it left an impression on the coin. Thus, the coin was "struck through" this object/substance, which looks to be a piece of metal.
