I did “Eeny, meeny, miny, moe” and finished on that one.
I see, I thought it was an educated choice….
The difference between nine 1921 no mint mark coins with no indication of the selling price of each and no measurements of weight, diameter, thickness or good enough photos to assess if they're real or the grade does not lend itself to an educated choice.
The mintmark on the alleged 1890CC looks very suspicious as if an altered O mint or the CC was added to a P mint example after the fact. The mintmark appears unnaturally elongated based on the photo provided.
All of them as long as they are genuine and the price is right.
I love coins. Especially silver, gold and anything really old.
