<p>[QUOTE="Conder101, post: 4617327, member: 66"]The OP coin does show flowlining. (the mint calls this "starburst" today) This isn't too unusual for early modern proofs. Frankly they used the dies too long and often repolished them to remove flowlines and then continued to use them. As for the spotting I think it may be possibly be the result of the coins being dipped and rinsed with tap water, the flowlines still holding some water and being the last places to dry and leaving chemical deposits.[/QUOTE]</p><p><br /></p>
