2007 PR-70 Presidential Dollars Originally $1500 On Coin Vault.

Anybody bought 2007 PR70 Presidential dollars from coin vault back in 2007 for $1500. I remember they were offering price difference refunds for people that bought them at those prices when the price came down. I did bough a set when they were down to $199.I feel dumb about it now but at least I didn't paid $1500. I still have the set as a reminder of not to buy graded proof set coins. I feel sad when I see videos of collectors showing off their collection of PR70 Presidential dollars and PR70 America the Beautiful Quarters. When are they gonna realized that stuff ain't worth much. I do have this coins but in OGP from the mint. Don't need to grade this types of coins. Wake up collectors that's it matter that is a suppose perfect coin? Just get a nice example of the coin you like. OGP is good enough.
