Where do the values come from, and why do only some coins have values?
The values listed are calculated, without any editorial input or review. They are likely to be different from those listed in any given catalog, and may be different when you look again tomorrow. In general, there are two types of value listed – the value for an average coin of the type, and for listed grades. An average coin is just that, a coin of average condition for the type. This may be Unc for a recent coin, or good for one which is several hundred years old. We are working to improve the values, but as with any catalog, you should take them as an indication only.
