Matin? Could you mean Martin?

Assuming you mean "Martin," the serial numbers put the manufacture of both of those horns at 1926.  Your Martin would be the Handcraft model, which could have some value depending on condition.  There is very little interest in old Holtons, and for good reason.

Checking closed listings on eBay for similar horns in similar condition is a good way to get a start on estimating its private sale value.  If your Martin Handcraft lacks a front F key, it might not generate as much interest from players as the ones with one.
