If the "one circle" chip is 39mm across and 28 mm diameter inside then it is the PD-SH and caries a value of "C" to "E" ($2 to $7 a chip) which I think is way too high; I have a number of them and related single circle chips and would be happy to get a few cents each. The embossed Airplanes are PT-AY (if deep and they appear to be) (PT-BD if shallow embossed) and are rated "D" ($4-$5) which again I think very high; I have several sets of them. Nice chips but very common.
