I am doing some DD to find the name of a broker that accepts penny stocks.
I sold a portfolio of penny stocks before the transfer took place, but it had been accepted. So there is someone out there who may be able to help you out, and I'm starting to dig in to it again.
What I remember is that it had a large account minimum. I got lucky the day I printed out my statements, because someone must have painted the tape on one of my stocks with a close at the offer on a big spread. Talk about fortuitous.
I also had to meet them face to face with a lot of paperwork required. I will post the brokerage account name once I know. It felt like a market maker more than anything and I never did business with them.
