... but more of a "how should I approach this?"
I noticed a little box on the table at my folks' house the other day, with the address of a small-time local stamp and coin shop on the top, so I inquired of my dad what he was up to. He said that he had some old "silver dollars and Kennedys" that he wanted to get rid of, having recently cleaned out his safe-deposit box. I told him that he should have me take care of it, that I'd manage a better price somewhere than he would at the chop-shop; and there the matter rested 'til today, when the box was delivered to me. The coins are of no concern (neither to you nor me) but the notes are pretty impressive, at least to me. I haven't inspected serials for neat patterns and such yet, but there seems to be some well-preserved stuff: 20 consecutive 1954 $2 notes that are almost all better than AU (I'm strongly tempted to say 18 or 19 are UNC), a number of (some consecutive) AU/AU+ 1954 $1 notes, about 15 1937 $100s in VF+, a couple of absolutely perfect (from my inexpert POV) multi-coloured $10 and $5 notes, and some assorted other VF (or so) 1937 stuff.
He wants me to render this into cash. Not for any good reason: he's made of money; probably he's just considering encroaching mortality, and thinking that he'll be saving me some effort after he passes on. If I can prevail upon him to seal the stuff back in a vault, perhaps I'll have it to pass on to my daughter. But if he really wants me to carry on, how should I do it? Buy a Charlton's and start piecing it out on eBay; or try to sell the mass of it to a reputable dealer like Colonial Acres? It's not like he needs the money to live, but a substantial portion of his fortune was accumulated through good sense and good management, and if I'm going to do this for him I'd like to do it right.
Well, that was long. Any suggestions will be most appreciated.
