@Gladiators001 - does that tear in the UR corner extend beyond the numeral "1" or does it stop there? The lathework makes it hard to tell. Still, it is an attractive appearing example.
My example piece for this thread does not appear at all attractive, but I think it has a good story. This is probably the worst condition of any stamp I have that I would wish to keep.

As you can see it is in pretty grisly shape, certainly nothing that would be the poster child for its kind. Yet, despite that, in 2011 this item provided the illustration for number 145-E1, the first essay of the Bank Notes portion of the essay section listed in
Scott's US Specialized Catalog. It was the only known example at the time.
This had gone unlisted until Siegel handled the "Lakeshore" collection in 2005-06. It appeared in the last of the three sales (S. 909, L 1216) and the prices realized show that it sold. Five years later, in 2011, it was offered in another Siegel sale where I bought it as the only known example. Because it appears to be an earlier die state of the die used to produce 145-E1C, its design parameters might be reconstructed. So, although the precise details of the design were somewhat open to conjecture at the time, I immediately made preparations to have it restored by a well known paper conservator. However, within six months an intact version of the same essay was offered, again by Siegel, and I was able to purchase it as well.

Now that we know precisely how this essay ought to look, a paper reconstruction might well yet be attempted. But so far I have not acted on that, and the torn and crumpled state of one of the only two examples known to exist remains unchanged. A sorry state, to be sure, but grand in its own way too.
