Hi John,

The one on the right is L1974 from the 1950's, valued from $21. to $30.

The one on the left is L1984 from the 1950s to the 1970s valued from $6. to $10.

I believe these values are for a matching pair.

These value's are from The Collectors Guide to Casino Dice, Las Vegas Edition.

I hope this helps.

Best,
Ralph
