周兄,您這是簡(jiǎn)化版的PCGS評(píng)分標(biāo)準(zhǔn)嗎?PCGS英文網(wǎng)站上的評(píng)分標(biāo)準(zhǔn)要詳細(xì)得多,另包括視覺(jué)效果 (eye appeal) 和原光 (luster):
http://www.pcgs.com/News/How-United-States-Coins-Are-Graded。MS69的標(biāo)準(zhǔn)是這樣的:
MS-69 - Must have very attractive sharp strike and full original
luster for the date and mint, with no more than two small non-detracting contact marks or flaws. No hairlines or scuff marks can be seen. Has exceptional
eye appeal. Copper coins must be bright with full original color and luster.
其中有對(duì)原光和視覺(jué)效果的要求,而且也允許有碰痕。本來(lái)謝爾頓的評(píng)分標(biāo)準(zhǔn)有四個(gè)方面,不只是壓印效果和磨損(劃痕等)。
