Hi guys, I'm Italian and I'm new here.

I have some NES items and I would understand only the value in $ (one by one).

- Nintendo NES Consolle + 2 Joypad + Original package (working, good conditions)
- Nintendo NES Zapper Gray&Orange (working, as new)
- Adventures of LoLo (only cartridge)
- Chip'N Dale (full package)
- Dr.Mario (full package)
- Paper Boy (only cartridge)
- Super Mario Bros / Duck Hunt (only cartridge)
- Super Mario Bros 1 (only cartridge)
- Super Mario Bros 2 (only cartridge)
- Super Mario Bros 3 (full package)
- To The Earth (only cartridge)
- The Legend of Zelda (gold cartridge, full package but without maps)

Thanks in advance for the help!

Read 44 times.. but nobody answered me..

The items with original packaging are worth about twice as much as the items that are just the game.

Another reason no-one may have indicated price is because value of European versions may be different than North American, etc..

Edit- I made my guestimates based on North American version.  I suspect the loose items are worth less and the packaged items are worth more.

If I was to guestimate:
Original system with packaging = $30 min. More depending on condition and version.
Assuming styrofoam and box are in good shape.   There are several different systems.  The Action Set and Control Set are the least valuable. 

Zapper = $2 to $3
Lolo 1 = $5
Chip and Dale complete = $10
Dr Mario complete = $8 to $10
Paperboy $5
Super Mario/Duck Hunt $2 to $3
Super Mario 2 = $5-10 (check the pins. If it has pins all the way across on the connector, you can sell it to someone who wants to convert it into a repro.
Super Mario 3 Complete = $10 or more since it has full packaging. There's more than one version, check the code.  The version ending in -1 more common.
To the Earth - $2
Zelda Complete $15  (depends on condition.  That box gets beat up easily because they stuffed it so full)

Note:  You would likely not get much interest among collectors since collectors would have all those, but you would get good interest from gamers because all of those items are good to play.

that Zelda if it's the Gold Cartridge new in box it's worth over $30.00. the Legend Of Zelda Gold Version is Worth More than the Grey version but its not Rare YET

a Nes With the Original Packaging goes for over $50 on Ebay.plus $30 is how much they sell Nes's without the box for on Websites like Amazon Toys N Joys and others.
