How rare is this glass

I went to my first auction house style auction on my birthday on Febuary 21, 2011. I had bid on a couple of items and won and the very last item was a box of 21 character glasses. I had always been interested in them and I had never seen these particular glasses before. I won the item for 15 dollars and later found out that each donald duck bordered glass retails for 95 dollars. I have been looking ever since and have not been able to find even 1 glass that resembles these glasses even on the internet.
