Wam on cam
Ebay is becoming flooded with these coins for sale. Also, there are a lot of mixed reviews as to how common these coins are, or not are. I have searched over 5000 pennies since finding my 1998 Wide AM. And as such, the value will increase exponentially as years tick by.
In this search I have only found a dozen or so wheat pennies. I live in KY and I get a good mix of all mint coins here. The rarity of these coins are not yet appreciated in my opinion.
I don't think there's a lot of future in them, it's just a lot of buzz right now.
