Rarest famicom carts

[Rob64]

Would Super Mario World on famicom be considered rare?

The JY Company 45-in-1 is more rare than the single cart itself.  It's also in higher demand since it has the full version.  On this forum though, I've seen the single cart version go for $45.

The single cart SMW is highly sought after but not rare at all.

That weirdo science and materials teaching cart (that wasn't a commercial release) I forget the name.  Hella rare and expensive!

Kind of hazardous materials and physical science..

Actually, there are two Konami teaching cart, a high school one and a college one. I forget the names, but I've got pics of both somewhere. I think the adaptor you need to play them is more rare than the games.

Maybe this is one of the ones you're talking about, JC, but there's that one that explains stocks (or something like that) to new employees, and it used the Family Computer keyboard.

I have a Gold Super Xevious with a Japanese label which has five Japanese characters on the top of the label. Maybe it's a special edition. I think it's pretty rare. I bought it dirt cheap, somewhere around $20 on ebay. I think I got it from Canada. The cart has one small crack on the side though.

Can you post a photo of that?

[UglyJoe]

All of the Super Xevious carts are gold.  I'm guessing the 5 Japanese characters are ガンプの謎?  That just says Gamp no Nazo (Mystery of GAMP), which is the subtitle of the game.  I don't think it's anything special.

[nensondubois]

I do believe that is the one I have. A photo? Not now. I need a camera.

. I bought it dirt cheap, somewhere around $20 on ebay.

I think you overpaid.

[manuel]

I second what nurd said.
I have sold my Super Xevious to UglyJoe for 5$.
