HUID is a six-character alphanumeric code unique to each hallmarked gold piece. It can be checked in the BIS CARE app.

How prices work

Why does a gold coin cost more than the gold rate?

A gold coin costs more than the gold rate because its price includes the gold’s metal value at the live rate, plus a making charge, premium and GST.

GST and tax
