It's ethical to say the cards were cut recently as whether or not they were cut recently matters to bidders and the market value. Also, many collectors won't consider at your local Kinko's to be 'factory cut.' Factory cut Topps cards means cut by Topps. I'm talking here specifically about Topps and Bowman type sheets, not Wheaties-- the latter is topic for a different post. A main difference with Wheaties type cards is they were intended to be cut by hand away from the factory. You cutting off a Ted Williams card in your living room is what Wheaties intended-- though you're doing is 60 years later. Topps cards were intended to be cut at the factory and the uncut sheets weren't made for the public.

In general, if there's information you don't want to disclose at sale as you have a fear it will lower the sell price, that's information you should be disclosing.
