So Rich are you saying that we can no longer claim that a marble was made in a definite period of history by a definite company? We are entitled to our own opinions about what we like to collect, but not our own facts. I get the line about collecting what you like, but you seem to be implying there is no difference between remelted CAC cullet and original CAC marbles?
Obviously in this hobby we sometimes can't say exactly for sure who made what, but it's fairly easy to distinguish between a remelt and an original, particularly in hand. If your definition of CAC is broad enough to include contemporary remelts of original CAC cullet that's your choice, but I think most collectors make the distinction not only to accurately reflect historical reality but also because our eyes can easily spot the differences.
