Worthpoint user assistance needed for iHop mugs

[GopherDaGold]

My fiance' has two of these milkglass iHop mugs. We searched the web high and low but found only a couple listings for these mugs on Worthpoint. Is there a kind soul here with a Worthpoint account who can provide a sold for price?
I don't think they are super rare or valuable but they show up a lot less frequently than the banded rim ceramic mugs.
Here is a link to one of the Worthpoint listings:

Here is a photo of one her mugs:


Thank you for any help you can provide,
