Gibson EM150 Mandolin

I acquired an early Gibson electric mandolin with dog ear P90  pick up when in USA over 10 years ago with the intention of learning to play !!!!

As a busy bass player I have even less time to play my Gibson acoustics let alone my mandolin so it is time to move it on.

Can anyone point me in the right direction to have this appraised as to value so I don't "give it away" but can achieve a fair price please?

Mandolin Cafe is a great online forum so I'd be doing some research on there first.

Mandolin is very much a minority interest in the UK and we've lost The Acoustic Music Company in  Brighton, who were probably the major European seller for high-end instruments.

I'd try Eagle Music in Huddersfield. They do commission sales but I don't know the specifics in terms of charges.
Thanks Basher I will try Eagle Music as Im in Yorkshire
