Hi all. Sorry if I'm posting this in the wrong section, just looking for a bit of direction. I'm looking to sell my trumpet on ebay and want to put it up at a fair price however I have no idea what it's currently worth. My sister bought it about 9-10 years ago for $600-$700 (maybe.. it WAS a long time ago lol) and then sold it to me for $300. In that time it's probably spent about an hour out of it's case. Yeah.. good investment that one The brand is F. E. Olds, serial number NA10M. I've spent the last hour trying to find out the price of the damn thing and cant find any answers anywhere and just stumbled across this forum. So please, at the point any information is helpful. Thanks in advance, Scotty.
