Possible Reconsideration Of Grade While Still At PCGS?

There's no harm in asking. Some of heavy hitters in the industry can get it done but whether or not you or I can is questionable. Do you have any pics of the coin?

I much prefer to grade my own, sometimes with the assistance of PCGS Photograde, for U.S. coins. Saves me having to worry about what grading result I may get for my U.S. coin.
An exception is, that if you want to sell a high grade high value coin, where the slabbing fees are justified, and are not a large proportion of the selling price.

TPG's are of much less importance with other than U.S. coins, and especially so, when sold on other than the U.S. market. I guess that it comes with the 'territory', if you are interested in coins of ALL centuries and countries, as well as coins of the U.S.

Have a look at the auction catalogs of British coin auctiuoneers for other than U.S. coins. None of them are slabbed.
