Nice find
Multicarts in general are not that hard to find nowadays thanks to the internet, but in the US they are much harder to find (and sell for more as well). Price really depends on which games are on them, and how many, as not all multicarts have the amount of games listed on the label. The lower the amount on the label, the higher amount of unique games usually, so I'd say you're in luck! The label itself is also important, and I've never seen your label before, so that would attract potential buyers/collectors as well. I think if you put it up on eBay, and eBay doesn't remove the auction for being a bootleg, then you can get around 30-50 USD for it.
