I'm only buying slabbed IHC and what I noticed is that prices are 50% to 100% higher than a few months ago. Comparing today, there are none for sale in the sold prices of the last 6 months and I'm comparing AU/MS today to AU/MS sold in the past 6 months. All are higher than the lower sold prices. But I'm only buying slabbed IHC so my basis is not everyone else's. I've also noticed a lot of prices are much higher than NGC or PCGS price guides.
