I found a a few search results for insc. q9 plat longbows which went for about 5k, but I wondering if an OS version would be worth more. Thanks for the help.

Sure, OS items always worth more than inscribable ones with the proper base. But this one's "easy" to farm. I'd say 15k (Maybe 20 if you really fight for it)

It's worth more than 15k but because of how common they are inscribable now that's probably the best you'll get.
