Hello,

I found this UMW Pin in PA, it's in Today's Finds. I was wondering if anyone could put a date on when it was issued for me ?
Thanks for your help, if you know anything about it please tell.
Keep @ it and HH !!

Believe that is United Mine Workers of America... Maybe 1900s-1920s?

1910

I'm not sure how some of you are picking these dates. The 1890 on the pin refers to when the UMW (United Mine Workers of America) was formed, not when a member started with the union. Unless someone can show that the pins changed design, the 20 years of service pin could have been presented anytime in the 20th century. The gold 50 years of service pin has the same design, just a little fancier outer rim, and that design would bring it up to the 1940's at the earliest. Their news magazine list 70 years of service awards as well, but I haven't found out if they had a pin for that.

The primary clue for dating this object is the specific form on its back for attachment to the wearer's clothing. That specific attachment form is known as a "Ballou Clutch-pin" -- which was invented and first produced by American partners Frederick Ballou and Melvin Moore in 1942, and patented in 1943. Therefore, this object cannot date any earlier than 1942. For confirmation, go to the following link and scroll down to "Type V Discs." Dating Metallic Insignia: Collar Disks

Thanks for the help, I was hoping it was earlier but it seems sometime after 1942.
