Not an easy one, if you look at the bottom of the 5 there is a possibility of creating a Zero, i think it will be a longer job than you think,, but it looks possible , but personally i would not let ai take over. I will have a look next week when im home from hospital, you may lose some small details but not much. The bottom and the top can ce created withe help from the bottom left of the 5 , and the uprights can be created from the vertical of the 1
no, unfortunately it only has 1,5 and 15.Have you got a coin with a zero on it in a similar style? it would be a lot easier to copy across than make a zero from the five, thats going to be a PITA to do with the shading.
