my dads been collecting coins and bills for over 3 decades, and recently its starting to rub off onto me...
when i say coins, i dont mean collecting twoonies and olympic quarters. coins that are in mint condition, coins with defects on them, coins made in specefic years....example, my dad recently bought a nickle from the 40's i believe off ebay and he paid close to 100$ for it.
the first bill i bought was a canadian 1$ bill from the early 50's where inside the queens hair is the image of a devil's face

may be hard to see there...but you get the idea....
