How to Identify the Long Island Tercentenary Half Dollar

Start with the obverse heads. A genuine Long Island Tercentenary Half Dollar shows two overlapping right-facing profiles — a long-haired, bearded Dutch settler in front and an Algonquian Native American behind — with LIBERTY curving across the top and E PLURIBUS UNUM along the lower rim. This paired-heads design is unlike any circulating half dollar of the period, such as the Walking Liberty half, and is the quickest way to recognize the type.

Confirm the reverse. Look for a three-masted Dutch sailing ship riding stylized waves, ringed by UNITED STATES OF AMERICA · HALF · DOLLAR, with IN GOD WE TRUST on a small banner and, most importantly, the date 1936 above the wording LONG ISLAND TERCENTENARY at the bottom. That inscription is the definitive identifier; if the reverse instead shows heraldic shields or a different scene, the coin is not this type.

Verify the physical specifications. The coin is a standard half dollar: roughly 30.6 mm in diameter, about 12.5 grams, struck in 90% silver with a reeded edge. A calibrated scale and calipers are the best tools here — a piece that is off in weight, diameter, or edge reeding for a silver half dollar is a warning sign.

Expect no mint mark and only the 1936 date. Every genuine example was struck at Philadelphia in 1936, so the absence of a mint mark is normal. Any Long Island Tercentenary half dollar bearing a mint mark or a different date should be treated as suspect.

Be cautious with authentication. Classic commemoratives are targets for counterfeits, artificial toning, and cleaning. Watch for mushy or doubled lettering, soft or incorrect design detail, a weight or color that does not match 90% silver, and harshly polished surfaces. For any higher-value or high-grade purchase, rely on reputable dealers and third-party grading (PCGS, NGC) rather than eye appeal alone.
