I have a 1887 New Orleans Morgan and was looking them up and saw there's a oval & regular O mint mark type. I can't tell.... it looks normal to me ,but I'm not normal so......lol.... So I thought I would ask for some opinions. Thanks
Yours is a round, medium O, which was the only O punch used in 1887. The oval O was used 1879-84, and then on a few 88-89 dies.
