Steve Jobs autographed Mac Plus?!!?

[Mars™]

Hello,
I do not know where to post this, but I have a Mac Plus that is autographed by Steve Jobs, Steve Wozniak, and about 30-40 other names inside the shell.
(Pictures linked)

How/ Where do I take this to get it checked out, certified etc.
I looked on google and found them to appear to be the real deal,
so what do I do next to verify?

Any tips are welcome.

These signatures are inside of every early Macintosh.

i thought it was just the M0001 series that had the signatures....

At first thought I would agree with you, assuming it is because they signed the mold. However I have another Mac Plus, same model, which does not have any signatures inside it at all. So that means they are not inside of every early mac, only on this one and I assume however many they used that mold on.

I have a theory, that the first X number of Macs off the first mold have this.
I am hoping to learn more from people on this forum.

Could it be a 0001 series only thing as tom vilsack said?

Another thing: It is shiney inside the case, which does not seem normal, as the other Mac Plus does not have the shine either.
