Additionally, it was also producing regular 2008 $50 Uncirculated Gold Buffaloes without the W mint mark. It also produced the 2008 $50 Proof Gold Buffaloes. On top of that, it also offered Fractional Burnished Uncirculated Gold Buffaloes with a W mint mark for the first time ever.
These Fractional Gold Buffaloes had a $5, $10 and $25 denomination. The same year, the Mint also decided to offer Fractional Proof Buffaloes with a denomination of $5, $10 and $25.
