Huh. How 'bout that. Impaired Proofs are like house pets that escaped into the wild. Fun finds. Interesting roll, for sure!
Learned here a couple weeks back that since 2012, San Fran has been producing low mintages of S mint Business Strike coins for circulation. I've found impaired proofs in my change, but these appear to be business strikes (no cameo). My eyes have been opened...
Hm. I forgot about that. Oh well. Still, finding S-mints in modern pocket change is interesting enough. Low mintages, you say? All the better.
@furryfrog02 I believe Furry said it was around 2 Million a year. It kind of feels like the limited West Point releases, only it didn't carry the same fanfare.
The business strike San Frans seem to range more like @Mark68 said. I don’t think any of them are over 2 mil. Edit: They don’t get much fanfare because you can only get them from the mint. Not released into circulation like the West Points.
That would make sense. Kind of like impaired proofs then...meant for collectors but found a pathway to circulation.
Looks like the 2008 is an Impaired Proof while the 2017 is and S mint Circulation find. Village Coin Shop: San Francisco "S" Mint National Park Quarter Set has published mintages 2008 Silver Proof State Quarters 1,192,908
Reminds me a little of what happened at the P-mint during 1956-1964 with the Wash qtr bus strikes on older/worn proof dies...the type-2 reverse, etc. Not exactly the same but in the ballpark.
I get a roll of S minted quarters every time a new quarter is issued. These are all business strikes. I have at least a roll per issue. This last on, the Tuskegee Airman, I picked up a 100 count bag. I received a bag of the 2015S Saratoga quarters and found 18 that had a partial doubled profile (MD as per John Wexler).
