Up for purchase is a Wilson Mike "Coach K" Krzyzewski Authentic Signed Basketball. NOT INFLATED 100% Authentic! In the summer of 1995, my younger brother went to Duke Basketball camp and ended up getting a Wilson Duke Basketball signed by Coach K with a silver marker pen. It has been in storage since that time. While I don't have an official documentation/certificate authenticating this item, it was signed during the basketball camp and I've included a camp announcement that was given at the camp to authenticate that this is authentic and proof it was signed during the camp. Now that the coaching great has officially retired, this item is any collector's items dream. Payment made by 4:00pm EST weekdays will generally shipped out the SAME DAY!!!!
