USDGC ROCS
Since 2001 the USDGC Roc has been the primary source of funding for the event. Each year Innova Champion Discs donates special runs of Rocs that are offered to collectors and tournament supporters around the world. In 2005 the USDGC began producing official collector guides to help preserve run information and ultimately the value of these discs. You can find links to each of those guides below:
2003
2002
*The USDGC did not begin to produce official collector guides until 2005. Information for the original “CE Rocs” in 2001 has been gathered by collectors over the years. Additional USDGC Roc information can be found at championroc.info

Official USDGC merchandise is also available at Disc Golf United.
