It's funny how tastes change. Anyone who is currently collecting certified Proof silver coins from the 1936 to 1942 era in depth can see that "haze is in." Coins with deep haze, to point where it impairs the Proof mirrors and the eye appeal, in my opinion, with no marks, are getting high grades from the TPGs and sometimes CAC stickers. I have seen a few of these coins with the CAC sticker which I would not consider putting into my collection. They are dull and ugly. Years ago coins with haze were a bear to sell. The comment one would hear was, "That should have been dipped before it was slabbed." As for coins of this era, I don't know. If the haze comes off, and the coins are bright, it's a good thing. If it doesn't, and they are still dull, it's been a waste of money, but at least you know what the true surface of the coin is.
