Porkchop, Here is what you stated on BP, I recalled it as I got a check also.
"They removed the dimes and any markers/trackers that had anything to do with the old Dimes from my Acct many years ago. In fact, the dimes have been out of my accounts for so many years I forgot that I owned them. Well, I think back in March, I received a check for around $16,000. I had no idea what it was for. But after reading the message boards, I realized it was from the dime payout. So there is a way to track old holders even without current markers in your account."
