<p>[QUOTE="Midas, post: 95591, member: 2761"]I think NGC has done a great job improving their slabs. I think they are the toughest material in the market and the hardest to break out. I wish they used a black backgroud instead of white as white will reflect all adjacent colors. Black is absent of color and absorbs all light energy, therefore nothing is reflected back in or directly around the coin. Anyways, Red Lincolns and White Morgans look great in the Intercept Shield holder (black) compared to white.</p><p><br /></p><p>I still believe computer/technical grading is a <u>near</u> reality. We have laser scanners that can scan within 10 microns. You can assign digital value points to x, y, and z data and compare it to a given database of x, y, and z data points. The delta values (change of) can be measured against. The greater the differance, the lower the grade. Here's a sample of a laser scanned coin...just for fun.:</p><p><br /></p><p><img src="http://www.taicaan.com/images/5_Pence_Coin_confocal_laser.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>As for a coin's color, we have instrumentation that can measure color more accurately than any human eye. For instance, go to your auto body shop or Home Depot. Bring in a sample and they can measure the sample using a <u>calibrated</u> and <u>consistent</u> light source. The reflection of this calibrated light is measured and calculated. Remember, reflection of light from an object is for all intensive purposes, color. Remember that your coins will look differant outside at 12:00 noon than in your kitchen because the light source is differant!</p><p><br /></p><p>So what is the given?

Laser scan all of these coins to come up with a collective average for 50,000 x ,y, z data points on the coin.
