Watch List notes:

Government of Hong Kong, 1 cent, ERROR NOTE PAIR, 1941, DUPLICATE SERIAL NUMBER ERROR A7170418, a superb find indeed. Of all the errors that are most difficult to encounter it is matching serial number pairs and given the age of this pair it is likley to be the oldest pair of identical number pair extant for Hong Kong,(Pick 313b), both notes graded PMG 58 in conjoined holders. Unique and magnificently rare and will be a crown piece for any collection of Hong Kong error notes!.

Estimate: HK$90,000 - HK$120,000
