Well, I guess I'll be the bearer of bad news, for whatever it's worth.
If I were to purchase this cart, I wouldn't pay more than $15 or possibly $20 for it, and that's solely due to the supervision brand on the shell. Without that, I wouldn't pay more than $2.
The thing is, no one really wants famicom multicarts. They're a dime a dozen, even old ones, and they need to contain something special to be worth something. I always clear out my multis to a guy in Poland for cheap, and I'm happy just to get the money, that's how hard it is to unload these carts (and basically everyone back in the day with a famiclone had a couple multicarts...)
Why are supervision branded carts harder to find, famicom wise? I'd guess because supervision mostly distributed in 72 pins areas, such as Indonesia. But in this situation, most famicom collectors wouldn't be interested in this, in particular.
Maybe on nintendo age or eBay you could get a higher premium from an unknowledable member, but with famicom collectors, it's honestly worth little.
