penny tattoos: link: http://www.bing.com/images/search?q=Penny+Tattoos&FORM=RESTAB#a some are very well done.
I am not sure if I want to advertising my hobby. Normal, when we have brand on our clothes or skin, we are advertising something. Thus, tattooing a product equivalent to advertising. Cool factor is 10, but in long term, it will be eyesore.
I like tats I could see maybe getting the design from a st gaudens $20 or a walker like they did with the French coin. I think girls with tats are hot too the more the better!!
