newbie question 2 - how much scratch

[Nek17]

Hi, newbie's question here: how much scratch/scuff is a sign of cleaning.

I am searching posts and reading Derek Francis Allen's 'Grading' book but got puzzled with one florin coin. I could see some very fine scratches on the blank all around head however I couldn't find same series of scratches on the head itself (including wear spot), and they both are of same lightness/lustre, the 'cartwheel' effect is also well noticeable on both sides - can this series of scratches be the sign of minor cleaning?

I will provide a scan later, the scratches are like this one - to the right of head:

Thanks.

OK, here is the scan of my coin - realized the scratches are not as visible as when holding it in hands, but you could still see some long fine lines around head (not the shorter ones, think they are circulation marks). Has this been cleaned?

Probably cleaned. It doesn't look very good blown up.

Thanks Rob. Is it correct that heavily cleaned/scratched coin will lost the cartwheel effect? I guess this one has been 'gently' cleaned but still left mark.

The so called 'cartwheel' effect is given to the iridescence seen on original surfaces. Cleaned coins will never have this.

Thanks Rob, that's the part confused me coz the coin still has the effect, it might be some rough cloth cleaning left those series of fine lines.
