The symbol of Double Dragons with one ball between them, means good luck and wealth.
Couldn't find anything except that reference on a fengshui - chinese coin site. World coins didn't have anything like this, not even in symbol identifications. Maybe someone else knows something about it.
Manchukuo (Japanese puppet state) Y#4 10 fen/1Chiao, cu-ni, dated TaT'ung 3 (1934), mintage unknown, 30¢ VG, 80¢ F, $2 VF, $3.75 XF, $12.50 Unc per 2006 33rd Ed. Those prices are probably low - I was happy to pay my favorite dealer about $2.50 for an F 3-4 years ago.
The 2009 JNDA catalog prices it at ¥150 (~$1.59) low, ¥400 (~$4.29) middle, and ¥1,800 (~$19.08) high grade.
