Pre-War Correction underway?

[Rhotchkiss]

I collect rare back t206s, and HOFers from 1900-1920(ish), so that’s all I follow and know. But it seems to me that more common, pre-war, HOF cards have recently sold at large discounts compared to what they were selling for before all this Moser/alteration stuff went viral. For example, the Matty dark cap PSA 6 pictured below sold last night for just over $3100, which is much less than any 2018-2019 comp according to VCP; granted there does appear to be small white fleck or paper loss on the chin of this one.

This nice looking card sold for about 33% less than other comps. While my t206 brown Lenox and a pretty t215-1 sold in the most recent PWCC auction for strong prices, those are super rare cards, I noticed that a number of higher graded, pre-war, HOFers sold for similar discounts. I have also seen recent, one-off auctions of solid cards go for well below the past year’s VCP average. For example, a pretty D322 Wagner 1.5 just sold for under $5k (should have been a $6k+ card), a different t206 Matty dark cap PSA 6 recently did not get a minimum bid of $1850 (compare this to VCP averages), a Probstein SGC 6, t206 Cy young portrait just sold for $5,804 (PSA 5s have been selling at an average of $8k), and a fairly rare SGC 3, e92 Croft’s candy a Wagner throwing sold for under $2k (a steal considering these rarely sell and the more common dockman back normally fetches about $1900 in this grade).

So, I have seen indicators that we may be in a correction in prewar. Thoughts?
