Surface Finishing

The quality of the surface finish requested is based on industry standards. In general blanks should be free from blisters, porosity and laminations which would adversely affect the quality of the coined product.
The terms and definitions used to describe and establish the surface characteristics and requirements for minted products are,

  • Ball Polished Blanks with a bright surface, lightly textured on both sides. This finish is achieved through a wet tumbling operation using polished stainless steel media and specific chemicals. These blanks can be used for proof and proof-like coins and medallions

  • Burnished Blanks with a shiny surface and a visible textured peening finish which is achieved through a wet vibratory operation; normally with stainless steel media and specific chemicals. These blanks can be used for proof-like and high quality un-circulated coins and medallions.

  • As Rolled Blanks with a uniform finish achieved during the final rolling stages without further mechanical or chemical surface treatments. These blanks can be used for un-circulated and bullion coins.
