Drawings!!!??? Buy a Brown and Dunn. Or at least look at one to see if that's what you want. http://www.antiqbook.com/boox/top/213430.shtml Maybe a little more looking and you can see what their drawings look like. Or I can scan a page for you.
If by this you mean designs (drawings) that are already on the Internet, you probably won't have much luck. I imagine everything will be digital photos.
Oooooooooo, nice drawings. My B&D is from 1975, therefore it won't have state quarters. And even the coins they do have are nowhere near the quality of those drawings,
Sometimes people aren't on 24/7 and it will take awhile for your question to be answered. I don't know of a site that has drawings for ALL US coins. That is....if you are talking about ALL US coins. If you just want current then try to search at the same site you found the state quarter drawings at. There used to be a place that had drawings of coins such as the Morgan dollar, SLQ, Buff Nickel, and more....but they weren't free. Speedy
Well you could have a look here if it is the State Quarters you are looking for http://www.quarterdesigns.com/
Erm, have you checked the US mint site? It always help http://www.usmint.gov/about_the_mint/coinLibrary/
If U have to be such an incredible artist to draw a coin, imagine the talent you have to have to design a stamp for a coin!! Then imagine what talent you had to have to design a coin like the Morgan before there was computers. It was all done by hand. That's talent.
