Interesting concept. What if you had a semi-circle but with the flat part on the bottom, like a setting sun? Then the crown could be behind that. I like #45 color scheme.
On 87-90, the ORANGE COUNTY stands out and over-powers the RARE COIN & BULLION. How would it look if the words were all the same size? How about if the RARE COIN & BULLION was stronger or bigger than ORANGE COUNTY? Thanks, Dennis
