I work for a museum and found this button in a file cabinet. We have no idea of its origin or if its a repro. Anyone out there can ID it for us, it would be appreciated!
I dug one similar and thought it was a oldie at first, (in my case thinking early 19thC)
Sure looks like a match for yours on the site CBG posted above.
I still haven't seen one with the lined rather than stippled background.
This one still lacks a green check. http://www.treasurenet.com/forums/what/264816-button-crown.html
