I came across a 1994 S in excellent condition. This is only the second time I've found a proof in circulation. My question to you is why would a proof be in circulation? Thanks in advance.
A stolen collection being liquidated A kid got into Dad's collection A really hard-up collector spending his horde A blonde collector spending her horde The wrong coin was accidentally picked up and so on - your joke goes here!
Most of these come from people busting up sets to sell proof rolls. You can even predict what date you'll find next by watching the bid prices for the singles and sets. The first time the total value of the singles gets higher than the set then you'll see some culls in ciirculation. There are other ways it happens but this is how most get there.
I have seen a number of proof coins in circulation. I would imagine they mostly come from kids breaking into their dads sets. Stolen would be another one.
This is an interesting thought. I suppose if you had a large collection of proof sets (enough to make a roll, say) and you saw that it made financial sense to break apart your sets and sell them as rolls, and you were strictly in it for the money, you would do just that. Break apart the proof sets and sell them as rolls. I wonder though why you wouldn't just sell all the coins as rolls or even singles? Surely a single proof nickel (say) is worth more on ebay, even unslabbed, than $0.05?
