民国三十年孙中山像半圆铜镍样币。 （错误标为 Y-362）。耿爱德相信半圆铸于民国 30 年，仅有样币版。保存佳，光泽充沛。灰色包浆，局部色泽较深。 (t)
CHINACooper-Nickel. 50 Cents Pattern, Year 30 (1941). PCGS MS-62. KM-PnC194 (similar to Y-362); K-863 lll. (Erroneously identified as Y-362). Kann believes that the 50 Cent pieces dated year 30 only exists only as patterns. This nicely preserved example boasts lustrous surfaces displaying lovely gray patina with areas of richer coloration.
