Coins can be fun to collect, I've collected since I was a kid. Now mostly silver or gold because they tend to appreciate in value faster than most other collectible items. It's sweet to hear a 96 year old collecting for the forty year old grandson though.

Nirvana two times in one weekend! That must have been a lot of fun. I never saw saw them live, at that point I was living in South America and I'm not sure if they ever performed close to where I living in Chile at the time!
