Quoted from MedievalMike:A reproduction would actually keep the values of originals higher over the long term. It would get more ppl playing that title. My most valuable comic book is a TMNT #1 which has been reprinted several times. I think some of the biggest buyers for a new MM will be ppl who own originals. I have a nice collection of Transformers that retain their value and Star Wars figures even tho new sets have been made. Personally I just got back into pinball. It's a much easier sell for me to tell my wife I am buying a brand new machine for 5 to 7k then buy a restored hot title at current prices.
Completely off target.
The value of a pinball is in being able to enjoy playing the game itself, not the rarity. Comic book and baseball card values are based on condition and rarity. There are very few MM 's that haven't been modified to conditions well beyond how they were born. How much would a TMNT #1 be worth if you colored in all the artwork?
The reason they are worth as much as they are is because they were underproduced due to the market conditions of the time. Only around 4000 were produced. The market could easily absorb double that number if not more. People for the most part buy pins because they are fun to PLAY(the whole reason for their existence) not to just look at and brag about their "originality". Fact is, hardly any of these machines are "original" anymore and nobody cares. It's about the PLAY.
If MM's get reproduced, the value of the existing machines will plummet. The 100% original condition machines will hold their value more but they will still drop.
