1924 $20 MS67 NGC. 
Only 0.2% of the more than 1 million Saint-Gaudens double eagle submissions that have passed through graders' hands at NGC have qualified for an MS67 assessment in the more than 30 years since that firm was established. 
This is one of those submissions -- a spectacular 1924 twenty dollar type coin from a mintage of 4.3 million coins, just three of which are numerically finer. 
Frosty orange-gold surfaces are nearly immaculate. 
Merely a couple of microscopic ticks are seen, and they are largely well-hidden within Liberty's drapery. The torch fingers, Capitol columns, and other devices are needle-sharp.
