What you have here, are two 1878 Morgan dollar tokens replicated in brass or silver. In the 1970s, various Casinos put these coins out as promotional advertising. The dollars were circulated through and could be used for slots,gaming or food as the casinos.
Based on your photo of the coins(tokens) and there description I would place a fair market value of $35-$60 each on them. They are very popular right now in the collectibles market.
