The satin finish was used for the mint sets from 2005-2010. The application of the satin finish on all mint set coinage turned out to be a big bust. As a result, the Mint discontinued the application of a satin finish in 2010. Beginning in 2011, all coins produced for the mint sets will have a brilliant finish. Chris
Well that's awesome! For coins not from the mint i figure it would be hard to tell unless the coins edge was otherwise in good conditon? If they were just worn off or not? Are there any other ways to confirm like die markers (on the edge of course I mean, as I know this is done as a second separate step)
I don't know. I'm not in the habit of collecting circulated coins. However, it would be my guess that it takes longer for the edge to wear down than it does for the obverse and reverse. When was the last time that a cashier gave you your change standing on the edge? Chris
Thats like flipping a coin. Some times their heads when they go in sometimes tails. I thinks edges done first. Oops. I'm wrong again. Edges second. I'm no help
Sorry! I've always been used to calling Mint Sets, mint sets and Proof Sets, proof sets. You assume correctly. Chris
