I know this was discussed to death a while back but I checked on getting certificates for my ACMG holdings. Ameritrade said that once I received the certs, I could not sell any shares until I mailed the certs back to them. Is this true? I knew, and understood, that you could not sell before receiving the certs, but after? I know some will think I'm dreaming, but if news came out on this thing, and it shot up to .30 or so, I might want to sell a few, ya know?
Can any of you who have certs confirm or dispel the information I got from Ameritrade?
