Adding on to the topic of government checks, here are a few I've picked up. They're not revenue usages; I just like them aesthetically.
The next examples show the same allegorical figure.
And just for comparison, the same figure on an RN (revenue stamped paper).
And a similar figure on a state government check. This one is lovely in that while you can't necessarily see it on the scan, it is printed in metallic bronze ink.
Lastly, a design I just love aesthetically. Unused remainders are fairly common, typically selling in the $25-35 range. Used examples are a bit more scarce. The two examples below, while at first glance similar, are different designs.
I'm a couple months late to the party, but those are fabulous checks @revenuecollector! I'm very partial to the BEP-engraved govt. checks and have a few of those myself.
Here's my latest acquisition with two nice vignettes and an RN-L5 imprint. Printing by American Bank Note Co.
The eagle turned out to have some microprinting, which dates the engraving to 1859 -- well before it was used here. So you don't have to squint, it reads "Entered according to an Act of Congress in the year 1859 by the American Bank Note Co. in the Clerk's Office of the District Court of the United States for the Southern District of New York." These days it would suffice to say "Copyright 1859".
