Pic is not very clear, but I suspect they are 1967 FM tokens, likely from the collector sets. In circulated or oxidized form as yours seem to be, I'd estimate the value at only $1-2 each.

The lot of chips in the previous post, however, should retail at $1000 or more, depending on the motivation of the buyer. You should have no problems finding buyers for most of these chips. I need the Thunderbird 50c chip. Please keep me in mind if you decide to sell, or post notice of the auction on the bb.
