Matchbox catalog, variants and market prices

Convention exclusive castings rarely show up at retail, trading instead through private sales and online auctions, which is exactly where Wheel64's documentation becomes useful. Each exclusive gets logged with its original release context, production numbers when known, and a running price history pulled from the secondary market where these castings actually change hands. Collectors new to convention exclusives can see how far prices have moved since release, while longtime chasers use the same data to decide when a listing is priced fairly. Because these castings rarely repeat, accurate records matter more here than almost anywhere else in the hobby. Wheel64 keeps that history intact instead of letting it scatter across forum threads and old auction archives.
