Importance of Having Items Authenticated

Increased Value

Having your signed memorabilia authenticated will increase the value of that item by at least 3X its current value, so the importance of authentication is a no-brainer! 

Proof of Authenticity

The majority of savy sports memorabilia collectors want to see proof of authentication before they purchase an item. Without proof of authenticity,  it makes it hard for collectors to trust that the item they are receiving is what the seller says it is.
