Selling in Virginia
Mary, welcome to the S & W Forum. I too am sorry for your loss. Your Dad left you with some treasures it sounds, as well as a burden if you are not really interested in keeping any or all.
It sounds like you have some interest in firearms as you joined as a bronze contributor so we thank you for that donation.
As far as disposing in Virginia, I have resided here for 32 years now, and bought/sold/traded firearms of all sorts, handguns, long guns, Military surplus, etc.
I do have a FFL but it is Class 03 which is curios and relics, meaning I can deal interstate with weapons that are 50 years old at minimum...nothing newer. I use Armslist a lot, because it opens to the whole State. You must be very careful as that site (as well as VA Trader) is chock full of scam artists. If you decide to list one or more, watch all responses and answer none that the responder just registered recently or even same day as your listing. Answer none that are "not registered". Be careful and do not give any private info re your address or anything else. Make sure you insist on a Bill-of-Sale (PM me and I'll send you a copy of the standard BATF BoS that I use.
This does bring up another question. Do have full ownership of all your Dad's firearms, or are you acting as Executrix for the estate? Does anyone else have any possible involvement from the proceeds of you selling the firearms? The reason I ask is simply that by using an approved Bill-of-Sale you, the Seller, are attesting (legally) that you are the legal owner of the firearm listed by serial number, that you have the legal right to sell it, that you are offering no warranty of any kind. In return on the same BoS the buyer is attesting that he/she has the legal right to own the firearm, and that he/she understands there is no warranty on the firearm. Both parties are attesting to the fact that they are in compliance with all laws.
Basically....if a potential buyer balks at your statement in your add that "must be willing to provide valid VA id, and sign a Bill-of-Sale" then run...don't walk from that person.
I have 4 long guns up on the site at this time, I just sold, and I have some out of state offers on the Garand, so it does take some time, and you will need to at least review your offers daily, even though they are a little slow to send notice sometimes. Remember, VA Armslist is a free site, so the website makes no money from you or the buyer, they just bring 2 parties together electronically and from there you are on your own.
I also will tell you to stay away from Cabela's Short Pump. They have actually gotten worse, not better, with the Bass Pro buy-out. The folks there are decent enough, but company policy dictates what they can do and they have no real freedom in buying or selling. Used to be a little (very little) negotiation room on what they were selling...now all gone....which is why the exact same firearms are sitting for a year or more.
If you take your entire collection to one dealer at one time then I believe you'll get the worst offer. You may have $30,000 worth, at "retail", and you may even think that well...$15,000 would be good enough...but in reality, you'll be lucky to get an offer of $5,000.
As far as "local" full 01 FFL's left they have dwindled to only a few left, and none of these brick and mortar stores even want to transfer FFL to FFL. The last remaining LGS in Hanover (the other 2 good guys closed forever last year), you probably know the name, charges $75 (probably now $100) plus Overnight shipping, plus full value insurance which adds about $125 to $150 to your price, plus the buyer has to consider his receiving FFL charges making the whole transaction more than what some want to do. You know the one down in Colonial Heights, and you maybe know the one on Hull Street, but again...a real full time dealer just doesn't want the "hassle" of transferring a firearm from your ownership, onto his BATF required books, transferring it OFF his books, to another, while additionally having to package and ship correctly, etc. and is going to charge you accordingly to make it at least worthwhile while he (or his employee) is handling your gun instead of working the counter and selling what he already has in stock.
Sorry for the long ramble, and you do have a tough decision. If you really want to think about a no hassle (to you) lump sum deal you can always call one of the above noted LGS and they will send someone to your place to view the collection and make an offer, albeit probably a low ball.
If you do have the time and interest to at least take a few cell phone pics and post here on the forum, you will get the best "qualified" value estimate ranges. Another source would be the Standard Catalog of Smith & Wesson, 4th edition, which has value ranges and other valuable tips, available on Amazon.
Finally, there may be some Members on this Forum that are full 01 FFL that may be able to offer additional assistance beyond my 03 C&R limitations for a reasonable fee.
I hope some of this helps you instead of further "discouraging" you, and please feel free to PM me if you have any local questions.
