I actually had an account with MTB back in the day. They partnered with David Chaum, guru of techno-privacy. Chaum had a place with Cypherpunks roughly analogous to Satoshi's around here, except he didn't have the grace to disappear mysteriously, and he very definitely had feet of clay.
Anyway, MTB offered accounts using Chaum's blinding technology, so the bank couldn't see whom you were paying, as long as it was another account holder. I don't think this would fly today, but that was before KYC etc. The experiment never really got off the ground, and it was terminated shortly after.
The OP has a piece of blinded ecash suitable for transfer to another MTB account holder, at least if you had a time machine and could go back to the 90's. They were all powers of two, hence the 128 cents.
