10 Dollars MAS, polymer

Singapore's polymer $10 has been issued continuously since 1998 under the People in Action series, with Note Printing Australia — a subsidiary of the Reserve Bank of Australia — handling production throughout. The two signature variants noted here, distinguished by whether the small house symbols beneath "SPORTS" on the reverse are solid or hollow, are unlisted in the standard Pick catalog, making them a genuinely useful find for specialists tracking die or plate states across the print run.

The solid versus hollow house distinction is the kind of minor graphic variation that slips past general collectors but matters for dating production batches.
