I don't know where you got that info Lightwire, but I vehemently disagree and I think that almost are pie-in-the-sky or I WISH I could get those prices. People take most of your posts as the true honest fact and these are made up or extrapolated off Ebay data where verbiage means nothing, but photos or having a coin "in hand" tells the whole story. Your "source" is so open to interpretation (was the damage in remarks, or the title or the description or just someone's determination that the fault was actually there). You should remove the post as it is very misleading and exceedingly inaccurate.
Electronically gathered data like that bears no semblance to reality. How bad are the scratches/damage/corrosion/surface? Almost all data gathered from Ebay via computer relies solely on the TITLE of the auction, not the photo or description, let alone the accuracy of the listing. If it's taken off Ebay, then they don't allow ICCS or CCCS certification grades to be listed in the title, hence would not show in what was gathered. A generalistic term like corrosion or scratch means nothing in "words" ... a photo has to show it. The information in your post reminds me the so-called "numismatic" guides and books put out by the Marketing Manager at Ebay, where all data gathered depends specifically on what the TITLE of the auction is and disregards photos or anything else. Those same books are advertised right here on this coin site and also bear no semblance to reality when talking about populations, scarcities or values ... they DO offer a long list of the different things offered for sale by Ebay.
One of the items in the list that I have the most problem with (and misleading) is the 62% for lacquered coins. 90% of all MS-63 and above 19th century large cents that are red or red-brown were lacquered at some point in their collectible life because that was the only way to keep them red. A very short dip in acetone and the lacquer is gone and you have a bright and shiney undergraded coin ready for TPG. Likewise with corrosion, which could be a light PVC green scum, build-up hard scum, dry flakey gree-white corrosion, or buried-coin corrosion. A single-word description in your table doesn't cut it.
I think that members of the site here would get entirely the wrong (and inaccurate) idea of what to offer for a coin when buying or what to hope for a coin when selling. I think it best to remove both your post and mine.
