Trader Dick's tiki mugs - Sparks, NV... value?

I've come across a set of tiki mugs marked Trader Dick's, Sparks NV. There are 6 tall ones and 2 short ones. Do they have any value at all? I just want to know if I got my money's worth. Sorry.. won't reveal what I paid for them til later :wink: Thanks!

5 dollar range for most Trader Dick's mugs.

Very plentiful and with long production lives.

I'm getting ready to list them on Ebay. What should I start them at? I just looked at them again and they're all in perfect condition. Crazing on all, but nothing major. Same as what I see on other vintage mugs. All but one have a gold sticker that says OMC-Japan. The lettering saying Trader Dick's, Sparks NV looks like they're vintage. Could they be from the 50s or 60s? I can't find anything online to research these mugs. Any further help would be appreciated. Thank you.
