This auction is for one prototype chip from BTCC Mint. These chips were never sold publicly.
There are several differences between the prototype and final release. The prototype has “2016 C Series” across the top where the final has “C Series” and 3 stars. The prototype has 3 stars across the bottom where the final has “www.btcc.mobi”. The wreath around the sides only has 19 leaves where the final has 21. The colours for the prototype are also a lot lighter too.
