Recently, my interest in it has been coming back. I don't want to invest any money in it - my idea is just to do something small. I want to collect quarters of all US states. Once I'm done with this, I want to collect a quarter from each year as far back as I can go.
And then we'll see from there... I'm excited about this. I will post again about this when I'm done collecting all the US States quarters. I currently have 41 US state quarters - I still need 9.
