It is 1924. You are the cashier of the US Denver Mint ...
How do you ship newly-minted 1924-D coins to the Minneapolis Federal Reserve Bank ?
You prepare a shipping tag like this, tie it to a canvas bag full of coins, and send it via USPS Registered mail:
This particular shipping tag is the only one that I have ever seen that is from a US Mint. I have seen similar tags for shipments between banks, but none with this unusual $2 Franklin stamp (which is quite rare when still on an original shipping cover or document). The $2 stamp is also the rarer black and "lake" color variant (most of this issue is black and carmine). The Scott postage stamp catalog lists this one as #547a. The tag also has a violet-brown $1 Franklin (Scott #518) and a red-violet 50-cent Franklin (Scott #517).
