I came across a $20 polymer note today with a Wilkins Poloz signature and prefix FWZ. I can't seem to find a reference to this prefix in the latest Charlton catalog (35th Edition 2024). The FWX and FWY prefixes seem to be missing as well. I am assuming that this is just an omission in the catalog? The bill is just a spender given the condition but it seems a bit unusual that it's not referenced anywhere.
