Flag of ScotlandBefore we left for Scotland, I ordered over $300 worth of British pounds so that we would have money for tips and such. (I ended up needing much more than that.) The bills looked interesting, so I thought I'd scan them to my computer. Over and over again I tried, but I could not get the scanner to work. Then I tried something else (an ordinary piece of paper) and it worked fine. I infer that there is something on the bills that prevents scanning, perhaps as a preventative to counterfeiting. Have you heard of such a thing? I ended up taking a picture of the bills with my camera. Speaking of British money, I brought home several tokens of each British coin: one pence, two pence, &c. See here for images.
