How much would you pay for this?

I hand knit coffee cozies and can monogram them or put like a heart on them. I made one for my friend, she went to UW and just moved to DC for a job so I put a W on it for Washington. It turned out cuter than I thought it would and am thinking about making an etsy account to sell them but I don't know how much I'd ask for them! It takes me about 1.5hrs to complete one, plus about 30 minutes to do a letter. 
As you can see below it's a lot of work with the double point needles since you need at least 4 needles working at once!
