Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. When the CLR boxes a value type, it wraps the value inside a System.Object and stores it on the managed heap. Unboxing extracts the value type from the object. Boxing is implicit; unboxing is explicit. The concept of boxing and unboxing underlies the C# unified view of the type system, in which a value of any type can be treated as an object.

The age of when the ball was signed does not determine the value. Supply and demand does. The value of the signature will rely on the popularity of the player that signed the ball, and how often he signed. If there are more collectors than signatures on the market the value will be high. If there are many signatures on the market and a lower number of collectors, a lower value.
The value may depend on which two players signed it.
The value of a boxing Ring Magazine can vary depending on factors such as edition, condition, and demand. Generally, older or special edition Ring Magazines can have higher value, especially if they feature iconic fighters or historical moments in boxing. It is recommended to research recent sales of similar magazines to get an idea of its current market value.
