@MotoCarlo is your distro a German, Brazilian or Chinese 009?
A good German distributor with no play in the shaft is worth $100-$150.* A Brazilian one about $50. The Chinese knockoffs aren’t really worth anything as a brand new one is ~$75. Knockoffs won’t have any label on the bottom.
* As with anything used, it’s “worth” what you can find someone will pay for it.
