Original Nintendo Gameboy Found Sealed in Mom's Closet

Recently, my parents decided to remodel their bedroom including their walk-in closet which was known as Santa's Hiding Spot growing up. The closet had become incredibly cluttered with years of clothing and other things that get tossed in the closet to get out of the way. In order to complete the renovation, they had to completely empty the closet of over 25 years of clutter.

During the clean out process, they came across one of my Christmas presents that never made it under the tree - a mint condition, sealed Original Gameboy Basic Set. This set was just the system and four AA batteries - no games were included. The set had shipped directly from Nintendo - there was evidence of the packing slip that had been affixed directly to the back of the box. The Nintendo silver seals are on both sides of the box. 

My parents don't know if they were punishing me by not giving it to me or they just forgot. This had to have been Christmas/Birthday gift from sometime between 1990 - 92. 

I will post pictures of the actual box once I bring it back from my parent's house. 

In the meantime, I am looking for suggestions for what to do with the Gameboy. I actually still have a functioning Gameboy and a few of the core games, but I don't play it. I am not really interested in keeping it unless there will be some great value to hanging on to it for another 25 years.

I've seen a few Google results for the price/value of the Gameboy but I am looking for a Cheapass perspective on what I should do with this ancient gaming device. 

Thanks. 

Depends really on what you really want out of it. If you are a collector like myself I would keep it for display. Would be amazing to add a sealed gameboy to the collection. If you are not so much into retro or are looking to get a ps4/x1 you could toss it up on ebay and sell it.

Again its really up to you. What ever you do I would not open it as you can find open ones for a dollar at garage sales. (I found 6 last year for that price).

Thats pretty awesome though that it survived intact this long though .

The only thing im worried about with that sealed version is the battery inside the box. Its probably leaked already which could be hazardous. But then again if you are a collector and will just be displaying it then it doesnt matter.

There is a ton of styrofoam in some of those older console boxes. I dont have a boxed gameboy but its 4 double A batteries should be sealed in a sort of shrink wrap as well so hopefully if they did leak a little its either sealed inside that wrap or only leaked into the styrofoam. but yeah if its going into a collection there is no way you would ever know.

I obviously won't open the seals, those two strips of paper are the only value to the whole thing. By not opening the seals, there is no way to check the status of the batteries or the Gameboy itself. There is no evidence of battery jizz on the box so I imagine they are sealed or haven't exploded. 

I am not much of a collector and I can't imagine my wife going for the "Original Gameboy Exhibit" in our house. I obviously am not going to open the box and I can't trust myself to sit on it for an extended period of time and maintain the condition of the box/seals. I will probably end up putting it on eBay, but I will have to do some research into pricing it. I want it to sell for the most money, but I want to flip it sooner than later. 

Other than google searching for the item and recent sales of similar systems, is there a place to get a good valuation on things like this?

Pictures please!
