<p>[QUOTE="physics-fan3.14, post: 3605919, member: 19165"]Good question! The short answer is that proof coins absolutely do also show flow lines. Take a look at the excellent proof that is the subject of another current thread: <a href="https://www.cointalk.com/threads/gtg-1962-franklin-proof-half-dollar.342579/#post-3605867" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/gtg-1962-franklin-proof-half-dollar.342579/#post-3605867">https://www.cointalk.com/threads/gtg-1962-franklin-proof-half-dollar.342579/#post-3605867</a></p><p><br /></p><p>You can see in the pictures of that coin that there are flow lines evident in the fields of that coin. This is even easier to see in hand. Proof planchets were polished, which reduced the wear on the die, but even proof planchets would eventually wear the polished mirrors off the die. Franklin halves especially are notorious for having weak, shallow mirrors and lack of cameo contrast. This happened because the dies were used to strike too many proofs. And yes, as you deduced, the dies were sometimes refinished! There is a distinct difference in appearance between the early strikes from proof dies and the "repolished" proof strikes.[/QUOTE]</p><p><br /></p>
