I did not know there was a Yogi Berra stamp.
I guess these were issued in 2021, which would explain why I can’t find first day covers on the USPS web site. But my local post office still had sheets of them.
Also, postage is 66 cents now. Good thing the Yogi stamps are forever stamps. After all, as someone once said, “A nickel ain’t worth a dime anymore.”
