The overpaying is across the hobby really, as the Bronze explosion is showing us. Many factors for this, but as my generation (approaching 60,) reach the age where disposable income is probably at a higher level than for any previous generation, (poss including the post war Baby Boomers,) that could have something to do with it. There's also the very real feeling that maybe its a 'last chance to buy' as new pedigree collections out there in the wild, waiting to be found and brought to market, must surely be getting scarce now. After all, it is 2021 and the GA ended more than six decades ago.
