As requested, here are the mockups for my cash set with the Tolkien influence. This was the first of my two custom sets. On the first side there is a Tolkien-inspired star symbol, surrounded by six small stars. I drew from the heraldry devices of the sons of Finwe - see The Silmarillion.

The reverse side has the H for my last name, two different sets of stars, and there's a watermark of the inner part of the star from the first side.

I spent a ton of time creating this set and, after almost 10 years, I'm still very happy with the results and don't have any regrets. Knowing what I do now, and having seen hundreds of different designs and learned a lot, there are a couple things I may have done differently (color swap between the .25 and $1 is the big one - but I was thinking inflation and the $1 was going to see a lot of use, so...) but, particularly with the Tolkien influence, this is what I was going for with my design.
