The top two are very thin and common. They are worth about $4-5 each and the more you buy, the cheaper they get. Larger & thicker markers, and ones with intricate designs and shapes may sell for a few hundred or more. Yours on the bottom is worth $10-15, IMO. Dale Seymour, John Benedict, Travis Lewin, Derek Cowan, Robert Eisenstadt, etc., are some of the more knowledgeable MOP collectors that I am familiar with.
