nice photo work.

problem is that since they are in the holder its hard to tell whats on the coin and whats on the holder. I'm not seeing anything here that says 70. I can point out on every one of these that would exclude them.
when you are talking a 70 you are talking a completely flawless coin with absoultely no marks, scuffs, rim marks, discoloration anywhere on the coin no matter how small as well as full and complete centered strike with no weakness on either side.
you're better off playing the lottery than spending $$ to crack them out and grade them.
