I was 20 and dumb and fell for one of those coin dealer traps, where they claim one is getting really rare coins for a great deal. I ended up paying about $600 for about $200 worth of coins. I was trying to compete with my mom, who collects coins, but I ended up getting a lecture instead.
On the flip side, this did make me smarter about coins and turned me into a coin collector - a hobby I've really come to love.
