1827 Curl Base 2

The 1827 Capped Bust Half Dollar with Curl Base 2 in the date is one of two principal date-punch styles used across an enormous mintage of 5,493,400 coins reported for the entire year. The Curl Base style features a 2 whose lower terminal sweeps into a soft curved foot, distinguishing it from the squared-off block style used on other dies that same year. This calligraphic detail originated from the date logotype punched into each working die at the Philadelphia Mint, and its presence allows variety collectors to sort 1827 halves into recognizable groupings cataloged across multiple Overton numbers. The Curl Base 2 dies were used alongside their Square Base counterparts throughout the production year, with no recorded preference at the mint for one over the other.

John Reich's Capped Bust design carried specifications that remained unchanged through this period, including the 89.24 percent silver alloy, the 13.48 gram weight, the 32.5 millimeter diameter, and the lettered edge inscription FIFTY CENTS OR HALF A DOLLAR applied through the Castaing machine before striking. Authentication of a Curl Base 2 example begins with examining the bottom of the digit 2, where the curved terminal should descend below the baseline and curve gently inward. Genuine pieces will also show the proper alignment of stars relative to Liberty's cap, the correct positioning of the date below the bust, and the die-specific diagnostics that match a particular Overton attribution. Weight verification using a calibrated scale eliminates most modern fabrications, since the silver alloy and planchet preparation of the early 1800s are difficult to replicate exactly.

Heritage Auctions records, along with Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) population data, show the Curl Base 2 varieties are available across most circulated grades without significant difficulty for general type collectors. Specialist collectors pursuing the complete Overton catalog treat individual Curl Base die marriages as separate targets, with rarity ratings that vary widely from common to genuinely scarce within the subgroup. Detailed information on the design lineage, die preparation practices of the early Philadelphia Mint, and how the 1820s halves fit within United States silver coinage is available in the Capped Bust Half Dollar series history.
