Five various punchmarks / blank. Large silver planchet, rare non-overstruck 2nd issue karshapana. 23mmx20mm, 3.25 grams. Gupta and Hadraker II XV A 2 (#289).

All 2nd issue karshapanas are extremely rare - these coins are considered to be a transitional issue between the large-flan 1st issue (coined under Ajatashatru and his ancestors) and the smaller-flan 3rd issue. The 2nd issue is the smallest out of all the 7 Magadha-Maurya issues, and the rarest one of them all. It is also not well-studied because of the small number of specimens available in museum or on the market. Over the last decade we sold many dozens of 1st issue karshapanas, 100's of 3rd issue coins, and many hundreds of 4th-7th issues, but we have come across only 4 or 5 second issue coins.
