Every brokerage has an in-house compliance that specifically holds and verifies your certificates.
There isn't a brokerage out there today who...verifies a cert; they just call the DTCC and ask for shares
I own 100% of the outstanding shares of shell "ABCD". I open an account at BULL Securities. I sign the back of my certificate and deposit those shares so I can eventually try to sell my shares into the market. Before those shares clear for trading, compliance makes a quick call to the T/A to verify that cert #1017 is in fact issued to me..and for the amount the cert states.
I'm still trying to figure out how Capital Growth did not see the conflict between Pamela and Stock especially when Pam had no formal paperwork filed to make her the official "T/A".
Brokerages do not "call" the DTCC for shares of people trying to enter their certs into the market. You think Capital Growth just called shares?
That's one of most ludicrous statements I have seen concerning how certificates enter the market AND how those certed shares are cleared for trading.
