<p>[QUOTE="SuperDave, post: 2233634, member: 1892"]Um, I think the OP's question was more about why they use toners for a "Grading Guide." It's a major distraction from learning about grading. At least to my mind, the reason toners are so prevalent in high grades with Classics is that original-surface coins tend to be toned after 150 years of care in a collection. How you keeping a silver coin blast white for that long? Not unpossible, but in that day and age of coal-burning industry and ridiculous atmospheric sulfur levels, coins that stay in the city are not staying white. For may issues I'm guessing they don't have appropriate untoned candidates.</p><p><br /></p><p>That said, those images are far too small to be of any use above MS65.[/QUOTE]</p><p><br /></p>
