I've seen discussion about "Mr. Lowprice" and his sales tactics before.
Seems his modus operandi is to put stupidly high prices on his items for sale ("There's no law against optimism" - Dilbert's Boss). He'll certainly sell at those prices if anyone is silly enough to just click the "buy" button, but will also sell at much more reasonable prices if you Make an Offer.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
This seller has been doing business on eBay with such an approach for a long time. Based on his feedback, he has had good success with it.
Looking through his feedback, it appears most of his items sell via "Best Offer." vs. original asking price. His approach isn't something I'd pursue, but it's hard to argue against his results - and, as others have said, he's not doing anything wrong!

This is the marketplace--the good and the not-so-good. That particular seller sent me an offer last year after I placed one of their coins on my watch list. I think the original asking price was in the mid-$300 range--very high for the coin, but the coin looked good. The offer came in at something like $100--still rather high but I declined. I don't recall which coin it was, sadly.
Each of us needs to be educated when shopping for coins, or selling them for that matter. The marketplace, wherever that may be, will never be a temple to honesty or virtue. I have purchased more than 2,300 coins from sellers and mints, and thus far no issues that were not easily remedied. If you are not willing to invest the time and effort to know what you are buying, then you know where the fault lies, it lies with thee.
The link comes up to a 1994 Veterans Memorial Silver Dollar. That one is very hard to find not hazed, clouded or toned, or even by itself. Oh well, the search goes on.
