Collector Strikes: Reverse Proof & Enhanced Uncirculated
January 28, 2015
As a collector, it is important to understand all of the different strikes a coin can have. Strikes can range from a regular, mint state business strike, a proof strike, reverse proof and enhanced uncirculated strike. Almost everyone is familiar with a regular business strike and even a proof strike. What about a reverse proof or enhanced uncirculated?
A reverse proof coin is struck exactly like a proof coin, but the the fields of the coin are frosty and the raised devices are mirror like. The term “reverse” doesn’t refer to just the reverse of the coin. The term “reverse” comes from the fact that the fields are frosty rather than mirror-like.
The enhanced uncirculated strike is a special strike that has only very recently been implemented by the US Mint. It’s not a business strike, it’s not a proof and it’s not a reverse proof. It’s actually a little bit of a mixture of all three. Enhanced uncirculated coins include three or more different finishes including mirrored surface, soft frost and heavy frost. The strike is done with a special laser treatment that gives it the one-of-a-kind look. The Mint has also indicated that there may be different finishes added in the future.
