What are these sites that are claiming $140 in good condition?
One problem in numismatics can be the use of language. At times our use of words is NOT the same as what most people are used to. When the average person describes a coin as being in "good" condition they mean it is very nice (although when it is actually seen we find that since they don't actually know what a really nice one looks like, they have overestimated its condition.) But to a collector, a coin in Good condition (notice the capitalization) is actually at the bottom end of the desirability scale.
