I used to get the grey sheet and give prices listed in there for certain types of coins that people asked about and didn't know it was against the law, I would think anything that was made public like that could be posted elsewhere just as long as you named the source of the information. If it is illegal I know allot of people are breaking this law because some
ebay sellers even list ask prices on the particular type of coin they have for sale on
ebay for all to see in their listing
