The first chip is an engraved clay poker chip called 'Rough Rider'. It's about 100 years old but not that rare. Retails for $3-5 in very good condition. I can't see any detail on the other two. If they are plain clay chips, they are very common, worth a doller or less to a collector.

There are quite a number of us who collect the antique poker chips. Please post the other chips you have, as you might have something the is quite scarce. Even the most desirable engraved and inlaid chips seldom sell for over $20-25 or so, though.
