Post Your "X" Replacement Notes (1973 Or Later)

Nice "tenner" Tee!
Here's a pre-toonie:

Nice, and here's its "sister"

-only we're now in the era of mobile tech so few collectors will bother to scan/photograph their collection. I only did a portion of my collection as I'm selling on my website (& ebay).
Here's a "tenner" I got from a "Lot" I purchased privately. I had no idea this note was part of the mixed lot since I was actually after a $5 test note (so the extra notes became part of the final purchase price/& a nice surprise later).

For sure. And here was another surprising banknote from the same lot (most of which were from the 1969-1979 series):

& I'm just realizing now it's the Crow-Bouey signature combo rather than the more common Lawson-Bouey ABX note.

Pretty common replacement (pre-toonie):

Here are a couple of $2.00 notes that I just picked up in the USA in a presentation box with a Toonie.

What would be a reliable website to find information about replacement polymer notes? Many replacement notes have surfaced on ebay, some of which are even certified, but I could not find a source where I can look up the prefixes.

If I were you, I would register with the Canadian Paper Money Forum since there's so much more info than just the SNDB.

Once you've registered you can then enter their Serial Number Data Base (SNDB) separate link from their forum.

You will get all the ranges of the Journey & Frontiers polymer series. Here's an image of what the top of the $5 table looks like (showing first prefix):



BTW: I could not find a copy of the Charlton Canadian Government Paper Money catalogue as they were all sold out but you could order 1 at Chapters/Indigo
