These sold last noght on E-bay for $255:
Smith & Wesson N Frame PRE WAR PW Service Grips Diamond Center S&W Deep Dish | eBay
A decent pair, but some imprefections to the rim of the medallions and general scuff marks. I thought a really good pair of these was valued at around $200, and a pair in this condition somewhat less, but certainly well over $150.
Two bidders at the very end bid these up. One bid $250, and the other $255 or more, how much more is unknown.
Maybe these have surged in value lately ($255 is over 20% higher than $200, and I wouldn't have thought this specific pair to be worth that.
