Hi stackin,
Wow, good investor you are at early age in stackin up old sports cards.
I started collecting stamps and coins at age 11 and hung on to them til around 20 years old then slowly lost them as i moved around so many times and I do not have any left...lol
You too! I got into stamp collecting also for about a year when I was 12 but it got boring to me and stuck with trading cards 😂
