I have a coin that appears to be silver, the size of a siver dollar. On one side of the coin it says, " Mayflower '70 " on the bottom," 1620-1970" and profile of a boat on the reverse side, there are 2 winged houses holding a family crest with a ribbon banner under it saying "Ged Be Ovr Friend" . It appears to be uncirculated.
The second coin shows the same on the front as the first coin with the reverse being aman and woman in colonial dress and a bow of a front ship and the front of a building with a sign saying " Island House ".
Any help you can give me would be appraiciated. I am trying to find the value of the coins.
