Nuts.
If you are a collector, and can spend $100K-$150K on a book without any hardship, and want the best copy known, and don't care what you sell it for at some future date, you STILL have to be a little nuts to pay such a high premium over the 7.5 Mask Comics #2 that sold for $33,600 in June 2021, or $42K more dollars than the same Mask Comics #1 sold for on June 2021.
There is nothing wrong with being nuts, "to each his own" and all that, but it usually isn't fiscally prudent. We all do it (I think). If you haven't overbid, and I mean overbid to the point of "what the heck am I doing still bidding" are you really a comic book collector?
