Carlisle Development Corporation

What Carlisle Development Corporation does

Carlisle Development Corporation is a privately held US software publisher founded in 1994 and based in Carlisle (Massachusetts-area code 978-369-4908). The company develops and sells desktop applications exclusively for numismatists — coin and paper money collectors — with the core line consisting of Coin Collector's Assistant (a collection inventory and valuation tool) and Grading Assistant II (a visual reference tool for grading circulated and uncirculated coins). The underlying technology is a desktop application delivered via internet download and running locally on Windows 7-12 and Mac OS (Mojave through Sequoia), backed by a curated proprietary US Coin Database spanning 1793 to the present, quarterly market values sourced from the Red Book (retail) and optional Blue Book (wholesale), specialized listings for Philippine, Confederate, Hawaiian, Colonial, and Puerto Rico coinage, and grading images annotated by a coin grading expert. All distribution is direct-to-consumer through a WordPress/WooCommerce storefront at carlisledevelopment.com, with email and phone support and a 30-day unconditional return policy.

The business model combines one-time perpetual software licenses ($54.95–$249.90 across core products and bundles) with recurring 1-year and 2-year subscriptions for database and market-value updates, plus add-on databases (Ancient Coins, Multicollectibles, World Coin Database) and a $26.90 companion book targeting retirees managing inherited collections. Customer segments are long-tail individual hobbyists: US coin collectors, paper money collectors, estate collection managers, ancient coin collectors, multi-category collectors, and retiree hobbyists. There are no enterprise customers, no disclosed institutional investors, no headcount disclosed, no parent company, and no public financial reporting; the company appears to be independently owned and operated with a continuous 31-year operating history serving a narrow specialist niche.

Emerging players

• Colnect: Free, web- and mobile-based collectibles cataloging platform covering stamps, coins, banknotes, and other categories with community-driven data. Comparable as a free, modern, multi-vertical alternative to Carlisle's paid desktop coin-inventory software.

Broad incumbents

• APMEX: Large online precious-metals and coin retailer with live pricing and a customer base overlapping US coin buyers and collectors. Adjacent to Carlisle as a downstream channel/partner and as a source of price benchmarks that feed demand for collection valuation software.
• Heritage Auctions: Largest US auction house for rare coins, with extensive price-realized data and an online catalog. Comparable because it serves the same serious US coin collector segment whose buying and valuation behavior drives demand for inventory and market-value software like Carlisle's.
• Numismatic Guaranty Company (NGC): Major US coin grading service with its own price guide and registry/portfolio tools for collectors. Overlaps with Carlisle on the US numismatist segment and competes indirectly on value data and collection tracking.
• Professional Coin Grading Service (PCGS): Dominant US coin grading service that also publishes price guides, population data, and a digital portfolio/inventory tool for collectors. Comparable because it serves the same US numismatist customer base with overlapping data (grade, value, identification) that competes with Carlisle's database and market-value features.
• Coin Dealer Newsletter (Greysheet / CDN): Publishes wholesale and retail price guides for US coins that the industry (and Carlisle's Blue Book wholesale values add-on) treats as reference pricing. Comparable as an authoritative US-coin data provider whose pricing content overlaps with Carlisle's database products.

Others

• Whitman Publishing: Publisher of the official Red Book (A Guide Book of United States Coins) and other numismatic reference books, plus coin folders and albums. Comparable as a long-established supplier of reference content to the same US numismatist hobbyist base that buys Carlisle's products.

Direct peers

• Collectorz.com: Publishes desktop and mobile collection-management software (Book Collector, Movie Collector, Music Collector, Game Collector, Comic Collector) on a similar direct-to-consumer model. Directly comparable as a small software publisher selling to hobbyist collectors via perpetual licenses and online delivery.
