Set up a table across the street and offer free "apraisal" services. And even if you don't want what the idiots are bringing by you can direct the ones who have something decent to a pawn shop.

Quoted: A woman walked into the local gunshop here and handed two nicely customized Colt 1911's to the owner and asked if he could have them destroyed for her.  Her father had died and left the guns, and she didn't want them in the house.  An honest man, he put the guns on consignment and gave her  the sales (less consignment fees).

Good man, most of shop owners would have agreed to dispose of them... by selling them!

Reminds me of something we were told in our pistol licensing course by a long-time deputy sheriff.  He told us to tell our families where our pistols were because some less scupulous deputies would read the obits every day and wait 31 days and pay a visit to any deceased pistol permit holder's family and ask where the guns were.  If they still had them they informed them they were breaking the law by having them for more than 30 days... by law they could arrest them, but they would just seize them instead.  If seized they would likely not get destroyed and would be kept.  If the family asked if they could seel them, they would inform them yes, but the dealer would have to come get them from the sheriff since they couldn't possess them any longer, and they likely wouldn't get more than some low ball figure.  Of course the deputies always knew somebody who would be interested in them, and would pay them what the dealer would and save them the trouble...  Be surprised how many people went along just to avoid the entanglements.

Deputy never indicated whether the crooked guys had gotten busted and that's how he knew about it, or was just a warning about a rampant problem.  Point was driven home.
