(1860) 2 Bu JNDA 09-28 Man'en 万 延 Meiji Type 明治型 AU58 认证号36807257, PCGS号860370

When purchased pop was 4/1, and at least one of those AU58 was just a Meiji Nibu in the wrong holder. Between January and April 2020 the populations exploded; all newly graded pieces I've seen have been misattributed. At least 59 MS62, 20 AU58, and all 3 MS61 are just Meiji Nibu. I have a suspicion the actual populations are much closer to original numbers (4/1). To date, I've found one correctly attributed AU58 (this one) and one MS62 (the first coin on CoinFacts as of August 20, 2022). Early Japanese Coins by David Hartill clearly shows how to differentiate between Man'en and Meiji, and the JNDA shows the difference between the Man'en Ansei-type and Man'en Meiji-type.
