I have a question on the many 'metallic' chips from Australian casinos, both the silver $1 and the gold $2 chips.

They are used at several casinos and I am told they are used as common table chips, right along with the 'normal' clay or plastic chips.

Does anyone know the proper, or common, designation for these mettalic chips?

Do they have a name, like 'Annuals' (they are dated and there seems to be a new issue each year), or 'Metals' , or ? ? ?.

TIA

Ken
