Herco BB mouthpiece. Rhodium-plated. If I had to guess, I'd say it's barely been used, and has just seen a few surface bumps/dings from sitting in someone's tuba-stuff drawer.
Tiny ding on the end of the shank, which I've photographed to make it look as bad as possible
Inside of the mouthpiece has some small dots of... tarnish? Pitting? No clue... I can see it, but can't feel it.
Also inside the mouthpiece, there seems to be some spots (bad plating?)... at the point the cup turns into the shank.
I have no idea what happens to Rhodium plating over time, so I don't know if this is normal from environmental exposure, if it is "wear", or if it's poor plating to begin with. Again though, based on the overall condition, I doubt this mouthpiece was used very much, and maybe never used at all.
Also, for a mouthpiece, it's pretty heavy. Seems Bach 18-ish in size, but I didn't measure it.
