Sports card manufacturers often encounter changes and delays in their release dates, although they rarely provide specific explanations for such occurrences. It is important to note that each card set is unique, and various factors contribute to these shifts. One factor is the inclusion of autographs, which can significantly impact the release schedule. If a company has almost completed a set and anticipates receiving a substantial number of autographs in the near future, they may adjust the release date to minimize the need for redemptions. It is worth mentioning that card companies are not particularly fond of redemptions themselves.
Another factor that influences release dates is the presence of supply chain challenges. Shortages of essential materials for producing modern sports cards have posed difficulties. Although the situation appears to be improving, manufacturers and printers are still striving to regain a sense of normalcy in their schedules. Additionally, the growth of the hobby has led to increased demand for production facilities, which can further contribute to delays, particularly in sets with larger print runs.
These are just a couple of reasons why the sports card release calendar is subject to constant shifts.
