It was by accident that I ended up with a collection of currency identifiers. Let me explain. Recently I started to research accessible currencies for people with visual impairment. It didn't take long to figure out that it will not make much sense on a theoretical level, because reading about it is one thing, but if I wanted to really understand accessible currency, I had to get my hands on a few.

Thus, I started to get a few different currencies with dots and other marks. The next part of the research was alternative identification of currency, when a bill is not identifiable by touch only. There are several methods, I wrote about it when I described how blind people recognize currency. You will also find pictures of some of the identifiers there.

The topic just fascinated me, and before I knew, I had a pile of different tools from many countries which blind people use to recognize currency.

Then the next logical step was to download all kinds of apps and software which uses information technology to use the same, so now I also have a pile of apps to recognize currency. Now my research makes more sense, and in the meantime I have developed an interest for a collection that is relatively hard to categorize. Fortunately I don't have to, I just need to enjoy it.

If you have any money identifiers and you would be willing to part with it, please let me know.
