Coin and Paper Money Collecting/Japan 1941 (Showa 16) 10 Sen Varieties


Krause catalog lists two varieties of Japan 1941 (Showa 16) 10 Sen coins, Y-61 and Y-61a.
They only differ in weight, 1.500 grams vs. 1.200 grams.
According to catalog value they are both about equally common.
But of the 8-10 that I have owned I have never had the 1.500 gm variety.

Does the 1.500 gm variety exist?
If so, is it rarer than the catalog would have you believe?

Hi Dave,
Although the 1.5 gram version does seem to be less frequent than the 1.2, it is still common enough to where their values are identical in most situations. You can google them by km#'s and find one of either variety for sale at any given time.
Thanks for the question! =)

My specialty is world coins from the 18th to 20th centuries, primarily non-US foreign coins and related areas such as errors and exonumia (tokens, medals, etc.). I can answer questions relating to identification, grading, selling, preservation and evaluation of such items. In addition to catalog value, I can give you the practical market value and trends for specific types of coins. I will also take questions regarding counterfeits (both modern and antique) and on how to identify them. I am NOT knowledgeable in paper money/banknotes, ancient or "shipwreck" coins. Thank you.
