Sooo me buying an Armorines #4 in NM shape (that say in a LCS for years for cover) is proactive or reactive? This is one example out of dozens....would it be proactive to know what a BS Plat looks like in case you stumble across one in the wild? We're not talking books that have been suddenly hot....
actually the best story was last year, I grabbed several large lots from an local online auction house that advertised over 100 comic lots. I paid less than cover for a lot that had multiple runs of Harbinger (four copies Harbinger 1), Magnus, Solar, Eternal Warrior, etc. This was last year, on comics that have been around for over two decades, some of which were always valuable (the Harbinger Pink from the lot is at CGC right now....)....
