Guide To Submitting Currency For Grading

First - I apologize for reviving a relatively old thread, but my question goes straight to the title of the thread -submitting notes to grade.

So the thread talks about what notes to submit - and what to look for. However, as someone that has never submitted paper to a TPG - How do you ship it, is there a form and specific packaging they require? To be more clear -I looked on PMG for instructions of how to ship it and I did not find any - and I could have very easily overlooked the link. The coin TPG's have very specific instructions about how they receive the coins.

Anyone have steps for that?

Thank you Steve ... as I said I must have missed it. I was all over the site and apparently was not paying enough attention to get there. I appreciate the reply.

For world notes PCGS Currency is much worse, I had a submission of 15 world notes take over 6 months to get graded!
