Tbh I am not seeing a 2 at all . Where is curve section that would pass through the top ball part and loop of the 6. I understand with the 5 that happens but there is nothing broken on the 5 you can see the down stroke is full and so is the top serif. So begs the question where did the rest come from. As for the 6/2 or 6 over any number of possibilities. If you look on the 2 where the left hand neck strats and the bottom serif you can see under the 6 both those points also the back of the serif on the right edge of the 2 is a visible marker point. Not saying it is there but those three points exist to the eye underneath the 6. It could also be purely coincidental. It makes it very difficult with any digit that has a 6 over it as for all intense of purpose it is like mapping over a 3/4 filled 0 if you get me lol. So anything under it would make it look like a filled 0 unless it had points to see like corners of 7's etc . Anything rounded and it is very difficult. I'll try see if I can get some better close ups as my new 15th magnifying scope turns up. Do not buy the lighthouse one for £167 absolute garbage.
