Acar was a sensation right out the box
Technically it took about a month for Acar and Tan to both reach $200+. There were a few dozen Anthony Tans go on eBay from X-Men Archives for under $100 for a few weeks then BAMN they were $300-$600. Acar was similar though people had the "Tan effect" on their mind so it didn't take long for $300 and eventually some reaching ~$1000.
Now Charles Hall was a sensation right out of the box but that was mostly due to Rittenhouse's significant spotlight/advertisements before Spiderman Archives hit the streets.
Food for thought. Bring on the new blood! *Old blood is good too... I'd just rather not swim in it.
