Visiting Colorado Springs (snowy there today!) and went to the ANA Money Museum. It's quite a place and worth the trip if you're ever in the area. It's naturally heavy in modern US coinage, including a spectacular collection of gold coins and pattern pieces. However, they do have an exhibit on the history of money. Here's their Roman coin display. I apologize for the quality of the photos; it was hard to photograph them through the glass and no flash photography is allowed (which would have made things worse anyway).
And just a few blocks to the East, you could have hit Ken Hallenbeck's coin shop. That's where I bought these two guys years ago which helped me down this path (I miss that town...)
