R2 Bank Check But Brown Not Orange Or Blue What Am I Doing Wrong?

Have a nice 1867 1st National Bank of Helena (Montana Territory). Is was written and signed by Nicholas Kessler- this was the 2nd brewery in Montana. If you ever need Brewery information you want a book called American Breweries II - which is also online at TavernTrove.com.

So, it has a 2c Bank Check stamp that should be an R2 R6? perhaps. But this is NOT an orange stamp. It is not even close. Maybe you could say brown on orange paper? I have not touched the color or contrast after scanning it -the ink might be a shade darker in person.



Am I correct in thinking there are no Bank Check stamps after the 1st issues? If so then I am stumped. Thanks, RnC

could it be very strong oxidation?

sulphurization

Aaah, Thank you.... So you're saying the beer was bad? haha...

This stamp has a minor double transfer in the bottom of BANK CHECK, most noticeable and the B, A, N, and E. Also a bit at the top of the US at the top. Nice territorial usage.

exposure to peroxide fumes will help restore the color. several methods have previously appeared on this subject in this forum. Don can set you on where to look.
