All I could find to add to my collection at a local show today were (top) a Kang Te 7 (1940) Japanese occupation Manchukuo cu-ni chiao/10 fen (Y#10); and (bottom) a Taisho 2 (1913) silver Japanese 10 sen (Y#36.2). I passed on another coin graded XF by the dealer, which had only a blob for the "year" character in the date - grease-filled die in his opinion, damage in my opinion. Sorry about the size differences in the photos. The 10 sen is ~17mm, and the chiao is ~20mm.
