I don't collect dice, so I'm not familiar with how they are cataloged.
Is there a listing of dice, like TCR, with catalog numbers? Nevada only, or other locations too?
Who does the cataloging & how is it published and kept up to date?

As for rarity ratings, I assume the scale goes from R-1 to R-10? Like the system used in Campiglia & Wells book?

Does the cataloging include price guidelines too, or just catalog # and rarity?

If all this is published on the internet, just provide a link and I'll check it all out.

I remember the time when Jeff Laudeman (spelling?) published his dice books, but that was a some time ago, before his untimely passing.
Haven't really paid attention since ... but I find dice an interesting area of casino collectibles.
