Why is it always so important to collect a "pair of dice"? It's always been that way.

In your pictures (and everyone elses), they always show two pictures of dice, even if the dice are identical. I can see the need if the 2 spot has one graphic and the one spot another.

I suspect the answer has something to do with using two dice in craps, but for collecting purposes, I wonder why.

Also, if you have a pair with a value of $200-300, does that mean a single is $100-150, or does a single die have less value that half because its a single.

Just wondering.

BTW: excellent looking book. I don't collect Nevada dice, but I might have to pick up a copy of the book.
