Thanks everyone.
I'm sure I will be let down while hunting for awhile. Lol. I watch several YouTube channels about CRH and have seen many hauls like this. Will keep you all informed on the next hunt.
I did search through them all for any RPM's and errors, but didn't find any. I did find a 1974 that seems to have a huge offset bubble that comes out on the obverse and reverse. There does not seem to be any damage to either side other than discoloration.
