Where to get a guitar valued

[Jasmine1234]

I have a bc rich slipknot guitar but can’t found them anywhere to get a valued online, is there anywhere I can go or ring to get an honest value on it. Thank you

I did a quick Google search for 'bc rich slipknot guitar' and got some results.

Reverb is a start, though the completed listings on ebay is often more realistic.
