1827 50C Square Base 2 MS64+ 认证号19897479, PCGS号6144

(CAC) O-131, R.2. The obverse with die line above the LI of LIBERTY, the reverse with "Leaning 0" in the denomination. This is a gorgeous near-Gem that is ideal for the type collector seeking a high-end Bust half. The strike is solid, if a trifle incomplete on the highest design elements, and the luster is warm silver overall with gold and violet elements at the borders. Purchased as MS64.

1827 Half Dollars have the third highest mintage of the entire series, exceeded only by 1834 and 1836.  However, they also contain some interesting varieties, including a 7 over 6 overdate and 2's which feature either a curled base or a flat base.  The Square Base 2 is the most common of the major varieties, by a significant margin.  This variety is common in all grades and can be found in Mint State with relative ease.  The most common Mint State grades is MS-63, followed by MS-62, then MS-64.  Gems are scarce and anything finer than MS-65 is very rare.  According to the PCGS Population Report (as of June 2011), the finest 1827 Square Base 2 Half Dollar is a single MS67.
