Early Ty Cobb Pin Identification Help Needed!

[Hankphenom]

So interesting. How about the backs? Do they look professionally done or by an amateur? They look pretty crudely done to me. The fronts look professional to my eyes, with the artwork, enamel, paint, etc. If it's an amateur, it's one who has access to some fine metalworking equipment and knows what they're doing from an artistic standpoint. To those who are guessing 1940s or 50s, what is it about them that suggests that? They look a lot older to me, but maybe that's just the oxidation. The orange could be a clue, but also, Tigers are orange, sort of, so the use of that color isn't dispositive as to age, either, I would say.
