Very nice (IMO: worth grading)

The consensus is PMG will grade it about 5 points higher but most CDN collectors expect this- so they often go with the more conservative BCS (if they wish to keep note/PMG if they wish to sell it). I have never tried PMG partly because I just don't understand why I have to join them in order to get something graded (and the fee structure seems complicated by the value of your note). With the fee structure in US dollars + shipping- it will be more expensive per note.

BCS is less expensive to grade per note (& you can pretty much trust it's been conservatively graded).

With whoever you chose, my recommendation is to get a batch (10 or more) done to keep costs down. I would expect BCS to grade/slab your note sooner than PMG too. (my 2 cents)
