Those buttons are hard to tell. I think Del is pretty much on track. I Googled what I thought it said and got no real results on it. Generally iron backed buttons were around 1900 or even a bit earlier and many of those buttone were reproduced on jackets even today. So the closest way to date it would be to see how deep the button was and to try and figure out how corroded other old items found there are. If you live in an area where just a few years corrodes steel, then it could be new. But if your ground is relitively mild to corrosion, then that button is probably older. Unless you find that particular style in a book, you won't know much more. I'll give Albert's book a try, but I don't remember seeing that type in there. :thinkingabout:
