Yup... that's how one gets hooked... coin collecting is not only highly addictive but a gateway "drug" to the hoarding of multiple items. Pretty soon, as you learn to recognize the good from bad, everything you shop for will become just as discerning. I walk into a pawn shop, garage sale or thrift store now and I'm an "art collector", lol.
Watch for unusual and uncontrollable tendencies towards: Marbles. Stickers. Patches. Tin cans. Bottle caps. Pins. Rocks. Breadbag clips. Stamps.
Counsellors are standing by...
