I was thinking a similar thing about value. I've seen unique and unusual items described on Heritage and such as "worth whatever it takes to bring it home tonight" or similar. One such note, I believe, brought $114,000 on a 15k estimate, so they really weren't kidding. This is an item that I certainly think would do better on Heritage or SB than Ebay (where I got it), but also feels like it could go for 10,000 one day and 1,000 the next, depending entirely on who's in the room that day. Either way, I don't plan on selling it.
Interesting that they were released both with and without coupons. I guess that would make my piece more properly Fr. 203a, because it necessarily comes from the with coupons version. Any info on what the print runs were for each? I did a little looking into surviving examples, and here's the S/Ns I've found. By appearance alone, I would estimate that all are the no coupons variety:
10174 (Joel R. Anderson)
20575 ("finest known", per Heritage)
26198 (mentioned in Stacks-Bowers sale of Taylor note)
29419 (Taylor Family)
That leaves just two that I can't trace. No coupons on any of the 5, and don't appear to have had them. It looks like the Anderson note, which last sold for $186,000 (!) on Stacks-Bowers, is about to come back up on Heritage. The Anderson listing on SB states that 136,000 were printed of the no coupons, so would that mean the with coupons print run was significantly less?.
I also did a little examining of issue dates, which are stamped in red on the note. All pictured notes seem to have April and May dates, including the Anderson which is 1,000 serial numbers below mine. That doesn't line up with the hypothesized January date here. Does that mean it's more likely a June redemption, or even a June issue date? If they were still issuing in June, though, coupon 1 would have been immediately mature.
