[QUOTE="GDJMSP, post: 37835, member: 112"]Well yes - but understand, there is a huge difference between flow lines and what are called hair lines. Hair lines are are just very fine scratches.

Luster on a Proof coin is different than on a business strike because the dies and the planchets for Proofs are highly polished to begin with. But the metal still flows when the coin is struck - and sometimes the lines show more readily on one coin than they do on others.
