They're definitely tough!

At the same time, obviously more than 1 was produced, so more could be found at any time. Along those lines, I have some that are 1 of 2, which are just as cool in my book, like the Mays 1959 Bazooka Complete Box, or the Mays 1963 Jell-O Complete Box.

This is the only one in known existence, a 1967 sealed Kabaya Leaf pack with Sadaharu Oh on back, graded a PSA 8.

As a matter of fact, here are the only 4 packs ever graded by PSA.

Please enjoy.

Well, not really a card, but it helped make the card...

1964 Topps Standup transparency

Perhaps this is pushing it a bit since it is more or less of a technicality, but this version of the 1967 Topps #252 Bob Bolin 'White Streak' Variation is the only one I have ever seen, and significantly different than the standard 'white streak' card*...

*Ignore the fact that they goofily label it 'white streak between name' (singular) and not 'white streak between names' or 'white streak between first and last name.'

While there are loads of Japanese baseball cards I've come across that may be "only one known", especially if they are not catalogued in the guide, here's one you may find interesting. Calbee put out special prize cards ("Homerun cards") in their sets, which were basically re-issuing the same card fronts with a prize back. In theory, every card may have a prize version, but I'm not sure if that's indeed the case, nor am I sure how many duplicates they issued (I have not seen very many).

To that end, here is one of the more famous Calbee cards, albeit in the rare prize edition. I'm not sure if another prize card version of this weird card exists.
This card is from 1977, featuring Sadaharu Oh and for some reason he's posing with "The Destroyer", an American wrestler who spent much of the 70s in Japan.
