Can you help?

I am trying to collect the alphabet. I have no reason for doing this except it makes me very happy when I find a letter. It doesn't have to be an actual letter, It can be something that looks clearly like a letter and it has to be found. Here are the letters Ive found so far and I just found a 'c' today on the roadside. If you find any potential letters laying around, please email me. (I know I'm sad but I cant help it, maybe you could support me in my sadness)
