[QUOTE="imrich, post: 2901224, member: 22331"]The "study" is a long term multi-year on-going process consisting of many coins which basicly show the same results of other independent studies, as that reported in the May 26, 2003 edition of Coin World. Individuals whined that those past studies weren't of large enough or diverse enough samplings. It's believed that a sampling no larger than a daily eBay Numismatic offering will prove the proposition of inequal grading standards. The proposition that couldn't be proven is what could happen when an expensive coin is believed "trashed" by a details slab, and then resubmitted to receive a grade increasing the same TPG publicly stated value (i.e. "price guides") multiple times. The studies have shown that grading reliability shouldn't be expected when using a TPG. It's believed there aren't uniform grading standards even within an individual firm for the same coin submitted repeatedly, much less between the two "premier" TPG firms. Independent published studies confirm what a daily study of eBay offerings will affirm. Recent inter-linked posts of mine (#38, HEY GUYS TELL ME WHAT YOU THINK) is an example that may show what can happen when there aren't checks/balances on a subjective system without objective standards. I believe any objective individual can locate similar possibilities in daily public auctions. The coins mentioned, questioned in the previous thread were handled as stated, with results as generally stated/expected for the individual circumstances. JMHO[/QUOTE]
