Kevin Cook has the largest dice collection and got the Guinness World Record to prove it. He has 11,097 dice with no duplicates. Every single one of those dice were different from every other die. In 1977, he started his dice collection with Dungeons and Dragons and expanded from there. After he had the Guinness record, Kevin didn’t stop collecting and on August of 2011, he was able to reach 35,000 dice.
