Kabu decks are single suited decks, generally using the suit of coins or batons. The usual composition appears to be a series of pips from 1-9, and a court card repeated 4 times. Some of the pips are decorated with silver overprints.
The decorated cards (right) are: 4, Ace, and 3. Rather inexplicably, this 4 is replaced by a 4 of batons!
Note the elaborately framed 2, and the court card, which bears a stylized soldier... complete with hat and scowling face (middle row).
