-UPDATE-

I figured it out.

https://www.ebay.com/itm/Lunar-Silver-Star-Story-Complete-2002-Sony-PlayStation-1-2002/382965192467?epid=63342077&hash=item592a811713:g:H6QAAOSwE9Jc5IGc

This listing shows the other UPC (735366106287) and it is the STANDARD version. You simply have the 2 versions mixed up.

Title of https://www.pricecharting.com/game/playstation/lunar-silver-star-story-complete should be Lunar: The Silver Star Story Complete Collector's Edition (or some variation of it).

Title of https://www.pricecharting.com/game/playstation/lunar-silver-star-story-complete-4-disc should be Lunar: The Silver Star Story Complete (they both say "Complete" but this one is the standard none box version)
