nice tag, one of the mechanics in my collection is same in Patina, dark rich green and could be mistaken for paint.
Congrats on your tags. It would behoove you to take your collection to the Charleston Museum and Avery Research center for Black Culture and have them looked at, documented as authentic , photographed and the whole 9 because I just saw a bunch of tags on this forum and %90 were fake.
The forgers are getting better so document it now before the forgers ruin the market on them. At least this way your collection will retain its value.
Hey, who knows, maybe they can loan them from you and pop your names up in lights for you in a display while on loan.
