Here's the $45 pair. https://www.gunbroker.com/item/1029329637

They're cast urethane reproductions. The back sides of BW (and brown) grips will give clues to their originality, but seller does not include a pic that shows the backs in the listing. Misshapen checkering (as in Greg's pic), holes that aren't threaded, and wood grain impressions on the back (e.g., the latter would indicate repros cast from wood grips) are some elementary red flags. If you have them in-hand, the hot pin test easily separates Bakelite from plastic--although not necessarily original from repro.
