This is an official commemorative keychain produced in 1993 to celebrate the inauguration of Bill Clinton as the 42nd U.S. President. The front features the American coat of arms, and the back features a relief of the White House. It has an antique-style plating that gives it a sense of weight, and it is in beautiful condition even after more than 30 years. This is a must-have item for collectors of American political history and presidential inauguration memorabilia. 1. Inauguration memorabilia are historical collectibles. In the United States, commemorative medals, keychains, buttons, and pin badges are produced for each presidential inauguration. During the Clinton administration (1993–2001), there was a high level of attention as the first president of a new era after the Cold War, and memorabilia from this period are gaining collector value as "post-Cold War first-term president goods." 2. The double-sided design of the White House and the coat of arms is a higher-end specification. Inexpensive single-sided print types (single-sided engraving) also exist, but the double-sided relief finish like this item is expensive to manufacture and is likely a limited distribution item for ceremony officials and guests. 3. The good condition after more than 30 years is rare. Many tourist souvenir models from 1993 have deteriorated over time, and those like this individual, where the engraving and plating are almost intact, are in the top class in the collector's market. • Short-term (up to 3 years): Stable popularity of the U.S. presidential history collection will be maintained. • Mid-term (5-10 years): Re-evaluation of the Clinton era (Cold War termination archive) will progress, and an upward trend is expected. • Long-term (10 years+): The preservation value as a tangible asset is high, and demand will be steadily maintained as part of the collection of successive presidents' series. → Predicted increase rate: +30-40% (10-year span) → The future market ceiling is expected to be approximately 5,000-6,000 yen.
