These just got listed an hour ago in Denver for $150 (Danielle Colvin, Wheat Ridge) which is a screaming deal for Iron Grip Dumbbells. 88 cents/lb is well below retail ($3-4/lb) and even secondary markets which are usually around $1.50-$2.00/lb. Not to mention shipping.
Unfortunately, I cannot even come close to justifying 85# dumbbells. In fact, I cannot remember using 85# dumbbells in at least 10 years.
They would be cool though.
