The other day a dealer had a bundle of about 30 Chinese 20 Custom Gold Units notes (P#328) with consecutive serial numbers.
These were in uncirculated condition and very 'crisp'. The serial numbers look to have been 'heavily' impressed.
On close inspection I noticed small, random, somewhat faded, spots of different coloured (pink, green or blue)inks on some of the notes. Looking on various sites I also noticed some others have similar spots and on some of the other denominations in the series.
At a catalog value of about $17.50 in UNC it could be an expensive investment for me.
So my question is could the ones I was offered be genuine? Does anyone know if these have been a target of counterfeiters?
