In these pictures the luster seems to be in almost pristine condition, except for some scuffing on the JFK's jawbone.
Although these coins are comparatively common in very high grades (because everybody kept them), It is still somewhat surprising that the luster has survived this well on a coin found in CRH'ing.
Weaker strike - some sharper detail has been lost on the higher points of the design, both sides.
Some smaller minor dings and some sulfide/oxide spotting.
Congratulations. I guess that is becoming quite difficult to find 90%silver in CRH'ing.
