The other man is too kind. If you can get twenty dollars for it. Sell !
Those Spanish reproduction muzzle-loaders look nice, but to shooters they are really kinda cheap black powder guns that were imported in huge quantities in the 1960s and 1970s and sold as kits in hobby shops for the buyer to put together and finish. If it's complete, not rusty or damaged and finished well it should get $50 to $100 if you are lucky. I see them at garage sales a flea markets a lot and that's the price range. It's what firearms collectors call wall decorations. Sorry, you don't have a rare antique. Hang it over the fireplace and enjoy it!
