I always wanted to collect coins from every country. I like the US quarter, different state has different image related to the state. If you want to see the image of each state behind the quarter, look here.
I just won a bid in Ebay that have 80 different US state quarters. I cannot wait to receive it and admire it. By the way, my moms like to collect notes. She has a huge collection of it. I wonder who she will pass it to in the future.
