<p>[QUOTE="Conder101, post: 994752, member: 66"]I really wish the mint had not started calling the W mintmarked non-proofs "burnished" becaused it did nothing but create a lot of confusion. As Doug mentioned ALL ASE and in fact all planchets are burnished before striking. In order to strike up well the planchets have to be annealed to soften them. But the annealing process discolors the planchets and coats them with a oxide layer. In order to get that off before striking the planchets are cleaned and burnished.</p><p><br /></p><p>If anything the "burnished" pieces are a little whiter than the non-"burnished" coins. But I really think that is the result of a finer matte finish applied to the dies than anything the do to the planchets. And after they strike some coins that finer finish is dulled and they start looking the same. I think you would probably be hard pressed to tell them apart if you can't see the mintmark.[/QUOTE]</p><p><br /></p>
