More than once, I've spoken with my wife about MyComicShop as an option. In time, I'll put a few more options to paper. This topic usually comes up when she expresses a concern that I'll precede her.
Trouble is, I have so much other stuff beyond comics that are a lot less liquid or widely-collected. If my boys have no interest in investing the minimum effort to realize a fairly sizable return selling these other collectables on the Bay or some other venue, then at least they can scroll through my phone and call any one of my numerous collectables contacts and at least give them to someone that gives a damn. A neat old cigar box, a rare pop bottle, an old B-movie poster, a fairly ornate old tobacco tin, my leather-bound two volume edition of John Marshall's biography of Washington, an early Hal Foster Tarzan Sunday page - even a comic - these are things with little to no intrinsic value; instead, it provides an eventual opportunity for the owner to become a prospective seller and maximize its potential. Invest little or no time, and you're likely to realize little potential. With a fairly minimal time investment, your ability increases dramatically to turn some of these relics into that month's utility bill, or a seemingly unremarkable clump of similar artifacts into a weekend getaway.
We're continually trading time for wealth in some capacity, and knowledge optimizes your return. I tell them this all the time: hopefully, they're listening.
