I am a pretty big fan of the 59 set, but not that big. Have the set, including the gray and white backs, a wax pack a cello pack, salesman sample and many uncatalogged recurring variants ( let me know if you want a list). No sheets or boxes.
Those are the first presentation boxes I have seen ( I am not in the market) and have no idea of market for them If you get the box do you need a presentation set too
I assume you have the Lucky Penny and Elect Your Favorite Rookie Inserts. Do you have one of the Lucky Penny key chains, and the First Annual Rookie Banquet Program ?
If you have not already done so you should visit the PSA Registry Forum on CU where there is a long standing thread on the 59 set. Don ( Mariner) there is my go to person on questions on this set
