According to Gregory Brunk in American and Canadian Countermarked Coins, Jacob Houck operated his business at the corner of German and Hanover streets in Baltimore, and advertised in the 1842 Matchett's Baltimore City Directory. His product, Houck's Panacea, was prepared from vegetable matter and cured a variety of ailments.

Two 1829/7 overdate varieties are included among 20 die marriages for the year. These were produced from a comination of 11 obverse and 16 reverse dies. The total mintage was 3,712,156 half dollars. This issue includes an extremely rare variety, O-120, one of the few die varieties not obtained by Russell Logan. Of the other 19, one is considered rare and two are quite scarce. The Logan Collection consists of 25 coins, including a major off-center example and this Houck's Panacea counterstamp.

The edge lettering is tripled with numerous overlapping letters.
