I've gone through a few collect/sell cycles, when cash flow was better, then I suffered some financial hardship that necessitated paring down the "accumulation" as it really wasn't a collection per-se, it was just an assortment of "good deals" or "that'd be neat to own"
unfortunately, i'm back heading towards a financial difficulty again, due to unforeseen medical expenses, and I may have to start making hard decisions again, problem is, i'm still pared down to a minimal collection, and anything further would really *hurt*...
there are about 5 guns that are family heirlooms that will *NEVER* be sold, there are some that are rare/hard to find now (H&R Topper Deluxe 20G single shot, CZ-452 Ultra Lux and Ruger Design Contest Winner 10/22 that I've done a few strategic, but reversible, mods to) and a "politically relevant" rifle that is currently under threat), amongst others in the Accumulation of Varying Size
On top of that, i'm still in a minor "minimalist" mindset no and have to fight off mild "hoarding" tendencies, and am planning on potentially moving to another house in the mid future, and would rather not have to transport a massive accumulation of durable goods to the next house, and further downsizing would help that, but replacing anything I sold now would be exceedingly difficult to replace...
the funds recovered in such a sale wouldn't last too long either as none of the sellable stock is particularly pricey, so if sold, i'd be out the firearms, the money would eventually disappear, and eventual replacements would be more difficult to acquire, so i'd end up with a smaller bank account *and* smaller collection...
..it's the same reason that selling my 1999 Yamaha V-Star 650 Clasic I got in a equal swap (traded my Jonboat for the bike) makes no sense, the minimal cash i'd get from the sale would be consumed in bills, and when I got out of the financial difficulty, i'd have a smaller bank balance, and no bike to boot...
at the moment, selling any guns is a short-term gain, long term loss...
