Re: what's a spanish cob worth?
Bell:
Minimum value is the intrinsic value of the silver or gold. It goes up from there--into the thousands. The values depend on the mint, assayer, denomination, condition, demand and a myriad of other considerations. If you have a specific coin in mind, there are many here who could give you their opinion as to its value--assuming good pics are submitted along with the coin's weight and average diameter.
