I'm not sure if it has been asked. In opinion do you think that error and varieties of cents will become more valuable over time? I just read they are also pulling cents out of circulation?
They'll get more valuable in nominal dollars - at some point, given inflation, even Zincolns and clad higher denominations will be worth more than face value as "bullion". But in terms of actual value, they'll be trivial longer than either of us are alive. Who cares if you can sell a roll of Lincolns for fifty bucks, if that fifty bucks still won't buy you a loaf of bread?
