How To Sell A Handgun Collection

[DEPUTYBILL]

A couple of things are not clear in your beginning post so a couple of questions.
Are you and these guns in CA?
Are you familiar with the CA Department of Justice (CADOJ) "approved for sale" of NEW guns list? It is a list of new guns that are allowed for purchase NEW at a DEALER.
You, a private party who already owns the gun, are allowed to sell guns that are not on that list if you sell them with what is called a PPT private party transfer. All perfectly legal, no problem. A PPT has to be done with both you and the seller face to face at a licensed gun dealer (FFL) who will do all the paperwork for the transfer. (transfer fees is likely to be $35 or so)
The reason I ask is if the guns are already in CA legally, and if they are NOT on the CADOJ list they will almost certainly bring a small premium over what they sell for out of state. The reason being, that PPT is one of the very few ways we in CA can get guns that are not on the CADOJ list. So, if they are not on the list and they are in CA, it is definitely worth your while to try to sell them in CA, using something like the page here on CalGuns or other CA connections.
Also, if they are NOT on the list, it may be difficult to sell them at a gun store since they can not sell guns that are not on the list. They CAN do the transfers for PPT, but they can't sell them directly.
So, for those in CA who want a gun not on the list, it would be a very nice thing i f you made them available to CA residents first.
Guns that are on the CADOJ list, you could sell most anyway you want, auction sites like gunbroker.com, gunsamerica.com, local gun shop, but just like buying cars, a dealer has to make something on it so a dealer will usually offer you less, but the convenience of selling them quickly and all at once.
We would love to see some pictures and brief descriptions if you want, and I imagine you will get some input about what they may be worth too.

I thought guns on consignment at an FFL were also exempt from the roster?
Am I wrong?

I am 99.8% sure that consignments are a PPT and therefore off-roster friendly. If you sell your guns to the LGS, they will be limited in who they can sell them to. (LEO, etc.)

There was some wisdom in advice of one of the CG'ers in that you may get less by selling the lot to a gun store but you will avoid all the tire kickers and low ballers/idiots; much like taking your car to Carmax and getting a decent price vs. selling on Craigslist and getting more money but 100 x's more headaches.

To OP, it sounds like maybe there is a family emergency or some kind of catastrophic health situation and if so, I'm sorry. Positive thoughts.

While I too have never sold a handgun, if I had to sell 25 guns, I would do this:

1. Put up the entire list on Calguns.
2. Give a sliding discount to those that buy multiple guns.
3. Put the rest up on consignment.

If I were to sell 25 handguns at once, I would do this ^

But You do have to do some homework so you can list a fair price on each gun to sell quickly while not losing too much money. Popular off roster handguns at a fair price would sell quick and the buyers are usually motivated to buy so you have less tire kickers.
