Well, how am I to know objectively?  I realize my scoop made in early 2025 (see that other thread) can't be beat, but it shows anything can happen somewhere, sometime outside eBay and Discogs. (And the lowest selling price shown in the Discogs statistics was below $50 after all.) And while the lowest current Discogs price you indicate at least is less than the "price when new", it probably - as in the case of Mosaic sets - all depends on how urgently someone wants that item. And how he values that (excellently done) book. Because 135 EUR for 4 CDs "plus a book" as such still is quite steep indeed, of course.  

Marc Myers' review in Jazz Wax. I do not concur with this particular paragraph (bold letters), but not agreeing with Myers happens quite frequently... "The newly released box is technically a sister set to Mosaic’s Classic V-Disc Small Group Jazz Sessions released in 2024. But there’s no comparison (sorry, sister). For me, the small-group V-Disc box was loaded down with flat, uninteresting and quirky recordings. By contrast, the big-band box is an astonishing and superbly edited collection of 218 tracks free from novelty material and packed with thoroughly exciting material, thanks to producer Scott Wenzel. What’s job Scott has done. Even bands you’re familiar with will impress you with some songs they never wound up recording for their record labels once the bans (there was a second one in 1948) lifted."

Two favourites:

So this is a good way to get an impression of Whiteman? I only have the Capitol sides:

Great, detailed research, as always!
