What would be the value of each of these horns below? (I want to get a good estimate or value in my head so in the future, I know that I am being fair)
Roy Benson 'Professional Rose-brass' Flugelhorn (Apparently a clone of a Yamaha and a flugelhorn player says that they play both the same but the Roy Benson is a much better value version of it, I have played it twice and it is in good condition. Bottom sprung valves in great condition, slides all free and trigger is operational. Bought for 500 US dollars four years ago.
Some old Graslitz Rotary cornet (Playable with a Ritter gig bag and a 1 1/2C cornet mouthpiece) Only 1st slide stuck, no issues. Bought in unplayable condition three years ago for 250 US dollars
Jinbao Rotary valve cornet (I never play it and is in good condition) All rotary valves lightning fast, good intonation and all slides free.
Bought new three years ago for 280 US dollars.
I think it is time I let these go, they just never get played and I feel sorry for it. Plus, due to the fact our house is pretty small, storage is hard.
