Now the market price is 700-800? Also depends on the appearance, whether there is really appreciation potential. In addition to the Gansu version and Lanzhou version, no matter what version the three-year-old big head is, there will definitely be a small tooth in the chest medal. I don't know if it's the calculation error of the carving technician or the special reserved feature, because the signature version of the sample currency has no teeth.

Either the stars are not obvious, or the bar lines are blurred, but the signature version is slightly obvious, and the year characters are different.
