<p>[QUOTE=&quot;TheFinn, post: 2881311, member: 90102&quot;]After working at a modern coining mint, I know that improper annealing of silver creates lots of problems.&nbsp; The mint I worked at was fanatical about the number of times the strips were heat annealed after each pass through the rolling mills and edge rimming.&nbsp; The results were no cracking, fully struck pieces and (with proper cleaning and polishing) NO MILK SPOTS.</p><p>Thanks for the two information bubbles on the cracking.&nbsp; After learning to pour molten silver and having some of it become brittle, I can appreciate what the smallest amount of impurities can do to the physical characteristics of silver.[/QUOTE]</p><p><br /></p>
