Found this beauty today, any idea on age?
"Standard Colour" are the only markings.

Probably 1810 to 1850 era. Stamping on the back of a button began around 1810 or so. Someone else should come along and give you a more definitive date, since I'm not a button expert.

Thanks, I did a little searching in past threads and it seems it came from Europe with the U in colour, but didn't know if there is any more someone could tell me
