Found this large flat button, measures approximately 33.33 mm ( if I did my math right). Has an intact shank and what looks like flowers stamped in the front. Found it at a late 1800's house site
Approximately 8 inches down. Don't know much about buttons, any info is appreciated.
Looks like a fancy dandy button. Given that yours falls into the 30mm+ in diameter and larger category, it dates to the 1770-1795 period, but were used heavily at least until 1815.
Pretty cool design too, I have not seen that one. Those over-sized late 1700's era coat buttons are normally referred too as dandy buttons. I agree with Iron Patch, they are usually a sign that you are at a good site when you find one.
