Abstract
A token is manufactured using a combination of minting or casting operations and printing operations. The token comprises a metal base material that is minted or cast to the size and shape desired including embossed or debossed areas at selected locations on the token. In selected recessed or countersunk portions of the token, there are provided thin disks of material capable of carrying printed material such as single-colored or multi-colored pictures or indicia. The imprinted disk portions of the token are covered with a first protective coating and, optionally a second protective coating, that eliminates wear and tear on the printed areas of the token. Additionally or alternatively, the entire token can be covered with an outer coating to minimize wear and tear and preserve the unique designs carried by the token.
