Using Jeff Lauderman's book if they are a red pair Late 50's early 60's valued at 8-14 dollars. An orange pair is mid/late 60's and a value of 14-25 dollars.

Now the Olsen& Johnson book lists them both as red and valued at 21-30 dollars with one exception. It shows the 60's pair as a two color logo.

After looking at your dice for a third time I believe them to be the earlier pair. Barry
