Blanks in base metal

RBI is the manufacturer of choice for small or big runsof circulation coin blanks. The minimum order quantity is depending on material or size but often already available from 1000 pcs.

With our high polishing this is also perfect for proof/collector coin series.

Electroplated coin blanks

A lot of central banks have shifted in the past to the cheaper steel blanks with Nickel, Copper, Bronze or Brass plating. Naturally RBI is able to supply this type of blanks also.
Our high quality plating, done with plating thickness up to 35um, ensures a long life time.

Nickel plated steel blanks, silver in color were developed to replace the traditional     Cupro/Nickel, Pure nickel and other silver colored base metals. Nickel plated blanks have good anti-tarnishing characteristics.

Bronze plated blanks, gold/brown in color with a unique conductivity.

Copper plated steel blanks, Reddish/brown color developed to replace full copper and bronze coins, in general used for the lower denominations for its lower cost per pc.

Blanks in Aluminum and Stainless Steel/Inox

These materials are a good alternative to base metal or even to plated metal blanks for the low value denominations.

This material has a good standard corrosion resistance by itself without surface treatment. Furthermore the weight is about 1/3 of copper based alloys.
Aluminum blanks supplied by RBI are slightly lubricated and therefore strike ready and very easy to mint.
Our sophisticated cutting and handling technology reduces damages on the blanks surface.

Stainless Steel
Stainless steel is heavier than aluminum, which gives a more valuable feeling. The material has a good corrosion resistance without surface treatment, a shiny surface and at low cost.


Flexibility is a great advantage and for us, there is no order too small and no challenge too big. There is no minimum order volume for blanks manufactured from alloys out of our stock, nor is there for special alloys.

There is a great difference in quality for blanks and we are able to offer any requested quality with regards to the thickness, weight, hardness and surface finish, all according to the requested coin or metal characteristics.
