Quote:The "s" circulating coins to my way of thinking are already in Dansco's
ATB album (including proof) #8146. It already includes the silver and uncirculated proof coins.
Incorrect. It has holes for the silver and
clad proof coins.

To my knowledge there is no difference between either the uncirculated proof or circulated coins.
Yes there is. One is a proof. The other is a business strike.
Quote:
Can anyone tell the difference between the two once they are out of either their mint holder or roll?
Yes, the proof will have an obvious cameo: mirrored fields and frosted devices.
Quote:
The "s" circulated coin is NIFC. Just like the current Kennedy halves.
Correct, these new Uncirculated S mint quarters are NIFC, just like the Kennedy half dollar.
