Well, just a quick GunBroker check (by no means a thorough or exhaustive search in any way), the above bolded prices represent a general value for these guns in average condition. The total comes to $5100. So your $83/gun cost turned into $425/gun value. And should their real value equal just half of this, $2550 still represents more than double your money.
So in other words, yeah, I think you done good.
Wow, I think some of those estimates might be on the high side. The 10/22s for example aren't in pristine shape. I'd say 5/10 maybe. I'm debating whether to stick with local sale or just throw them all on GunBroker starting at $150 no reserve and roll the dice. Locally, it seems like no matter what you have to offer everyone will offer you an AR or old shotgun in trade
