acceptable batch number for DC'd Brass?

[eowyn797]

Hi ladies!

i've never seen a batch number like this and i was wondering if it was any indication of inauthenticity or what have you.

it's for the old DC'd Brass pigment: 9B171

everything else about the jar and box seem fine, so i'm curious. thanks!

I don't have a valid batch number for brass, but if I'm not mistaken, many older pigments have this type of batch number format

This is indeed authentic. I have a Brass with the exact batch code/format! This is a really hard pigment to find
