You Vs ICCS 1938 Dollar

Good catch purelywasted, those notches in the fully formed rim aren't uncommon on specimens. I believe the reason for this is the slow careful strike, causing the beginning of the denticles before the planchet expands more in the collar displacing the metal and leaving it right above the denticles..where it sometimes doesn't fully strike out in the rim.

Edited to add: you can see something identical to this on the obverses of the Cook PCGS SP64 and the ICCS SP64 when checking heritage archives.

My assumption is that the reflective surfaces were written off as cleaning and resulted in a net grade AU50 instead of a MS60ish cleaned..when of course the coin isn't actually cleaned but is just a specimen. I can see how this one could trick a grader who is trying to bang out a bulk submission from a dealer.

AU-55, shows signs of either circulation or mishandling.

Unfortunately the coin graded AU50 again..I wonder if perhaps he saw this thread or remembered the coin from whoever previous submitted it...it's got everything going for specimen.. unfortunate. Time to try a different TPG and cross my fingers!
