[Solved] Best image matching algorithm for accuracy?

Question

First you shoud have some template denominations.
Let us say you have those at same scale.
Then you may try template matching using Normalized Cross Correlation (NCC) to find out how each of those denomination is matching with yourcurrent doller image.
Even though NCC seems simple, it can do wonders in reality.
the one which gives best matching score is the denomination.
You may try with both templates you have on your speciman image to be more robust.
It does not matter if it is 4 bpp or 8bpp.
