Codyiac: Welcome to SOTW. I agree with most of Grumps' questions even though you did write "silver."
The serial number is a low one, meaning the horn is early '20's and lacks the more desirable roller G#. A button-G# is not a fatal flaw - I've played TT sopranos from that era and they played fine.
The shape (curved, straight, or tiopped-bell) is critical as is whether the horn is LOW PITCH or HIGH PITCH (should be stamped on the back near the serial number). And if curved, does the horn have keying to F3?
A complete description is necessary if we are to offer a pricing range (which in itself is a WAG). DAVE
