No, but you've changed the parameters. We've gone from bog standard at 10x market value to an unattributed variety at a fair price.
If you mean I've looked at one of their coins at a hugely inflated price, and one of their other coins was an unattributed variety, I wouldn't have seen it in the first place because I'd have moved on.
If I think a coin is a good price, I look at the seller's other listings to see what else looks good. If it's a terrible price, I don't bother. I can't look at everything.
