Great subject! I haven't done a skin mount in probably 5 or 6 years now. I get $25 (might go up soon) per inch for a one sided wall mount plus anything additional like driftwood, name tags, lily pads shipping and crating etc. I offer a skin mount price but no one hardly bites and thats just fine with me. I usually charge another 2-5 dollars per inch more for skins. If someone wants a ped. mount, depending on the species i'll just add another couple hundred dollars to it plus the base, maybe more. When people call and gripe because of price its all good with me. Thats just more free time to catch my own fish for a change.
