Yep, lower part looks like it is indeed doesn`t have the number
Not to mention " ... spokeswoman for Spink & Son told that the medal has been confirmed by several experts to have belonged to Chiang"
Where it came from?!
"Several months ago, someone came to Spink & Son's Hong Kong branch seeking to auction this medal. The experts we turned to are certain that it is authentic," said spokeswoman for Spink & Son.
Sounds reliable
By the way, in 2011, a collector from Taoyuan also claimed to have Chiang's Order of Blue Sky and White Sun with Grand Cordon, which was purchased around 10 years ago at a cost of NT$8 million (US$267,053), the report said, adding that it was later sold to another person (sounds like there are too many Chiang`s orders )
So how much for the start?
