1954 $20 Consecutive Notes Top Grades

Not the Devils Face .
Hard to give a grade of paper currency from a photo but the value could be $75-80.00 each. I don't think it is worth getting them graded as the cost would eat up most of the profit.

Anywhere from AU to MS64.
$50-$80 each.
You can't grade higher grade notes from photos.
You must grade them in hand looking along the surface of the note.

BCS would be the best (& cheapest) but I agree with 'JimmyD.' 127,000,000 of these were printed so unless they're GEM UNC 66 "Original" or better, they won't fetch a huge amount of dough (so might not be worth the hasle/cost of grading IMO).

BTW: all banknotes (with the very rare exception of Euros) are issued with consecutive serial numbers- so nothing special there either. Nobody who collects currency gets overly excited about the normal SN stuff IMO. The only exception to this rule is the actual rare (10 or less) stuff.
