I had a sinew backed osage Plains horse bow sell for $1,700 once. But that was because the purported N.A. bought it off me for $200 and turned around, claimed it was his, and resold it!!!
If I could box up my scruples and put them in storage, I could sell sinew backed hickory board bows over in Germany for $1,500 all day long and overnite on Saturdays. All I would have to do is trump up some fake documentation on Native American Ancestry. But I am a little bit honest down deep inside somewheres and can't make myself do it.
Pricing of bows has a lot to do with how you are perceived by the buyer. To a great degree you are selling the sizzle more than the steak. Band sawn run of the mill oak with a single strand of artificial sinew to hold the bend sells for $400 at a local Native American art gallery here in town. They won't hold up even as good as the rubber suction cup kiddie bows sold in the dollar stores! I turn out a museum researched replica of an actual artifact, a shooting replica to boot, and I am lucky to get $5/hour for my work (not to mention nothing for my materials). Face it, tourists don't want to buy a bow from a sunburnt gingerhaired Scandanavian. So they are obviously NOT a market I can tap.
But now and then a real archery fiend will find me and start talking about getting one of my bows. If they are willing to stick to the conversation and really work out what it is they want and expect out of the bow...well, let's just say end up with something that is almost a gimme.
