I have a bar top that has been covered with clear acrylic. I would like to cover over the acrylic because it has pictures, old bar coasters, etc. underneath. What is the best method to cover the acrylic and still have it functionable as a bar top?

I am sorry that no one has come along to address your question yet!

Have you thought about stripping off the existing acrylic finish? It can be done, but it would take a lot of work. The other alternative would be attach thin, laminated wood to it and then stain, if you want to, and definitely put a protective coating on it of some kind.
