1818 8 over 7, Large 8

The 1818/7 Large 8 Capped Bust half dollar is one of two recognized overdate varieties for the year, distinguished by the larger of the two date logotype sizes used at the Philadelphia Mint that year. The overdate occurred when working dies originally cut for 1817 were repunched with an 8 to extend their useful life into the new production year. The underlying 7 remains visible inside the loop of the 8 on properly attributed examples, and the Large 8 reference identifies the specific date punch used. Capped Bust specialists collect both the Large 8 and Small 8 overdate varieties together, since neither variety can claim completion without the pair. The 1818/7 Large 8 is the more commonly encountered of the two overdates.

The coin follows the John Reich Capped Bust specifications used throughout the series, with 89.24 percent silver content, 13.48 grams of weight, and a 32.5 millimeter diameter. The lettered edge inscription FIFTY CENTS OR HALF A DOLLAR was applied before striking, and the edge should show clear, sharp letters on authentic examples. The variety is cataloged across several Overton numbers including O-101 and O-102, with attribution depending on confirmation of the underlying 7 and identification of specific die markers documented in the Overton-Parsley reference. Authentication should examine the date area under magnification, since later die states partially polished the overdate diagnostic. Weight verification combined with examination of obverse crack patterns and reverse letter spacing provides the standard checklist for confirming authenticity, particularly on cleaner higher-grade examples where altered date counterfeits occasionally appear.

Market demand for the 1818/7 Large 8 is strong because the variety carries Red Book recognition and is attributed on Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) holders. Heritage Auctions and Stack's Bowers offer examples regularly in major Capped Bust catalogs, with certified populations concentrated in the Very Good through About Uncirculated range. Mint State survivors are genuinely scarce and command significant premiums, particularly examples with original gray surfaces and strong central detail. Among the major 1818 varieties, the Large 8 overdate offers a more accessible price point than the Small 8 counterpart while still delivering the visual appeal of a clear overdate diagnostic.
