In order to determine age it would be necessary to know if it is one piece or two. Most of the enlisted man's hat pins are two pieces. But the very early ones were one piece. FYI that is know as the great seal. It was adopted in 1902 and is still in use today.
I thought the Great Seal or Army General Service Button had to be two piece because its post-1902.
Have you seen this thread? It started out normal enough but has since grown into a nice page for Great Seal button identification. I need to update the list someday just havent had time. http://www.treasurenet.com/forums/what/112828-great-seal-button-backmarks-help-3.htmlCongrats on the Great Seal button! I never tire of finding these and have yet to find two that are identical. They are a fun thing to collect as finds because of all the different makers, small variances in design, and materials used. My favorite are the WW1 eras because of the nice patinas they develop in the ground. Once you get into the WW2's they seem to get a bit monotonous. My favorite is a small 15 mm GS button by C Kenyon Co., which is a dark chocolate color and the only one that has that look.

I believe the screw backs were hat buttons. i have seen many. http://metaldetectingforum.com/showthread.php?t=232678Was just reading through it and bookmarked thanks! I need to add mine one of these days. Just a few weeks ago I found an unusual one. It's a 15 mm screw-back GS. Haven't seen another like it and I'm thinking it might have been a special issue.
