So, what would I try to buy if I had several million bucks of money?
Well, I did think of this a little, but really all of my imaginations of what I could buy if I had the money involved somewhat smaller sums (like a thousand or at most ten thousand dollars).
After seeing this thread, though, I did think a little more about it, so here's what I would want to buy, if I won...
$500: that Kideksha commemorative from 2003 because I was in that place and loved it, and a CC-mint Morgan for the remaining money if I find one (if I don't, a Philadelphia gold dollar).
$1000: a gold dollar from either Charlotte or Dahlonega, or ideally both (but that's unlikely), and a few Soviet proof commemoratives for the balance (they go for $5 each over here).
$5000: gold dollars from Charlotte
and from Dahlonega, as well as from New Orleans if applicable; a full-ish set of Soviet proof commemoratives; a CC-mint Morgan (preferably AU-58); the Kideksha coin; and a
Flying Eagle cent in AU-58 if the balance is enough for that. Oh, and a Columbia half (the one from the 1890s) if there's $100 left.
$10,000: this is tricky. If I see a Sestroretsk copper ruble, I'll go for that, and spend the balance as per the $5000 option; if I don't, I'd try to get as much of a US non-gold type set in AU-58 as possible (you probably realized by now that AU-58 is my favorite grade - it's as high as it gets with actual circulated coins; but if a particular type is cheaper in MS than in AU-58 I'd probably take the cheaper version). Also, if a Columbia half in AU-58 is avialable for the remaining money, then that. Oh, almost forgot: from this option on, you can assume that I
start with the Kideksha coin, and the Soviet proofs won't be far behind.
$50,000: I think that by that point a full 7070 set (minus maybe some of the rarer gold) could be assembled in AU-58; I say 7070 set because it frees me from trying to find a Chain, Wreath, or Liberty Cap cent in AU-58 - I doubt there are any of
those around! If there's enough left, I'll try to assemble a set of the so-called "classic" commemoratives, ideally also in AU-58 (probably won't get very far).
$100,000: See the above? That except better. And if there is such a thing as a "type and mintmark" set, I'll try to do that (should just about be enough at that point if I don't try to get an AU-58 for the rarer combinations).
$500,000: OK, that's where it gets into "I have no idea" territory. Half a million dollars doesn't really sound like incredibly much (and indeed a great many individual coins were sold for more than that), but there's that problem that 1) I don't want coins with no dates on them (which takes care of nearly the entire Ancient/Medieval region), 2) I don't want coins in any higher than AU-58 (unless that's cheaper, which can happen with some of the commemoratives), and 3) I'm not very interested in gold coins outside a type-mintmark set. That pretty much only leaves upgrading the type-mintmark set above to as many AU-58 coins as possible, getting the rarer commemoratives, and finally getting some rare type coins from my own country.
$1,000,000: With that sort of money, I'd just walk into the Taganka coin market and buy entire bargain bins at once. And probably much of the rest as well. Then I take the remaining money and buy whatever remains of the sets above.
$5,000,000 and more: No idea. Really. Seriously. I don't think I can
imagine that kind of money. :-)
