Got them in the mail yesterday! I was able to sort them by type and will go through to cherry pick as time allows. Most of the coins were aluminum or zinc, so there were a LOT of coins for that 2.2 pounds!
Here is a readout of what was included, in order of most to least:
50 sen, small type 1947-48 (probably 75+, grades F to XF)
10 sen, 1944 zinc type (50+)
10 sen, 1940-43 aluminum type (25-50)
10 sen, post-war aluminum 1945-46 (30+)
5 sen, post-war aluminum type 1945-46 (30+)
1 sen, imperial crest bronze Taisho/Showa (25+)
1 sen, bird design aluminum 1938-40 (25+)
1 sen, Mt Fuji aluminum 1941-43 (25+)
5 sen, aluminum war type 1941-43 (20+)
1 sen, 1944 zinc type (20+ and most ruined by zinc rot)
1 yen, 1949 bronze type (20+)
10 yen, Taisho/Showa sacred mirror type (10+)
1 sen, Meiji dragon (5-10)
5 sen, 1944 zinc (5)
1 sen, bird design large bronze 1938 (4)
1/2 sen, Meiji dragon (3)
5 yen, pigeon/ temple design 1948-49 (3)
10 sen, bronze waves design (3)
10 sen, holed nickel early WWII (3)
50 sen, large bronze 1937 (3)
5 sen, bronze waves design (2)
5 sen, WWII zinc 1944 (2)
5 sen, Taisho/Showa sacred mirror (2)
2 sen, Meiji dragon (1)
1 sen, Taisho rising sun (beautiful chocolate toned XF/AU)
Lot also contained a handful (10ish) of 1 and 4 mon coins, one that I need to work to ID, and a French IndoChina 1/4 cent.
So between this lot and the coins I already have, I believe I have an *entire* type coin set of Showa 1926-1989 (excluding commemoratives and patterns) and a good chunk of Meiji and Taisho. Now to sell the duplicates to have fodder for the silver
