I have 5 colors of the viking ship but haven't seen one with a serrated edge before. Serrated edges are not uncommon in generic poker chips, but not found for every design.

Your red dog-head chip is a good find (Seymour PA-DA, value:g). I haven't seen one before.

The leaf design could be a new find, as I don't see it in Seymour, including the 2001 update. You might pass it by RobertE to see if he has seen it before.

If those are your first antique chip finds, you have the beginnings of a very good collection!
