NGC Update for the 1997 Khan 5 Yuan Silver version:
272 graded specimens analyzed
1 variety unknown because no image
1 "Parentheses" with no image but label "1997 CHINA GENGHIS KHAN PARENTHESES - SERIES II" (so unverified)
36 "Parentheses" (thereof 10 with label "1997 CHINA GENGHIS KHAN SERIES II")
234 "No Parentheses" (thereof 112 with label "1997 CHINA GENGHIS KHAN SERIES II")
272 represents 10% of the actual mintage estimate of about 2700 (Ge Zukang).
With 37 of 271 being about 14% and 10 out of 122 being about 8% I "guesstimate" the "Parentheses" variety in the 200 to 400 mintage range.
2 "Parentheses" had a "1997 CHINA GENGHIS KHAN NO PARENTHESES-SERIES II" label

Any opinion is appreciated!
