Quoted from xTheBlackKnightx:

This is inaccurate, but common wishful thinking by new owners.
Original MM games in equal condition sell between $2-5K more based on regional markets. No sparkle required. Just solid, working, complete, and clean.
Remakes are not worth more than original either, unless they are junk, and even partial games can sell for over $4-5K, as a competent dealer knows how to do a playfield swap with replacement parts, and slap new decals on a cabinet. They do it with glee and double their money.
Values of originals are slowly on a return rise. Remake values are falling, as NIB remain available for those who wish to purchase.
This is not unique to MMr or future game remakes, but applies to all remade games until flatline collector value is reached, with a handful of exceptions based on extreme rarity and collectibility.
People do not buy remakes to collect, they buy them to exclusively play. It is a different type of owner in the current market.
It has nothing to do with quality of construction, extra features, or bling. It also does not mean originals are not played and kept as coveted objects either.
