I've taken to some of my old hobbies. Technically there's a difference between coin-collecting and numismatics - the latter deals with all sorts of currency, which would include collections of bonds or promissory notes. At one time I had a fascination of old paper currency, and I had started a small collection. Right before a family trip I decided the safest place for it would be in one of the many books in my house. Which was a good idea except that soon after that we moved house, and I had completely forgotten which book it was placed.
Here's a small sample that didn't go through quite as well as I had hoped through the scanner. These are the various 10 baht coins I collected during my two years in Thailand.
