I've never sold any mint secondary PCA $1's for anything close to $1/chip (including just recently) and I've sold plenty, probably close to 1000. All of mine have gone for $75-$85 per rack. Too many in circulation, and not a real popular spot/color combo or mold (RHC). People listing these for $100-$135 on eBay are dreaming.
However, picking up a rack of mint $5 PCA secondaries for less that $150 would be a steal. Even mildly used fivers still command at least that price.
