From 98 to 2005, we had a great selection of hard-signed stuff, even low-end products like MVP and OPC had hard-signed autos. Long odds, but it kept the value decent, and it was special to hit them. There were some great auto sets made in that era, I still have a few MVP Prosign and OPC Stanley Cup Heroes in my collection.
And for the basketball market, I have followed it a bit, the Prizm madness, people grading basic Zion cards like crazy, people rushing into retail stores to clean the shelves, it was the same kind of Covid madness as the toilet paper hoarding.
