I have entered a number of IND $5 notes and all had the signature of Wilkins-Poloz including the high note of IND 8966255 (33/33). Regarding the new signature of Macklem, it is different from the signature of the Macklem - Carney notes. I have compared the signature of AHU 3921288 (51/51) and with GMG 8204013 (46/46) and it is typical of all of us as we age, our signatures become less distinctive (more straighter than wavy).
