Never heard of it so I checked some Wikipedia pages, I learned our good old Atari 2600 referred to as such lol.
Since it even has its boxes and if it's in great condition you may sell it as collectors' stuff because such stuff with boxes (boxes are important yo) and damn even with their manuals fetches for a high price, but naturally the price depends on the standard price decided by natural price balance of 2nd hand market. You gotta be able to prove if it actually works, otherwise it may be deemed as another scam seller thingy.
Most importantly its price depends on your country. For example not many people would buy that in my country because it's considered a "shit console", but in your country it may be even way more popular than NES, Sega Genesis and PS1 due to its cultural significance (which is why here boxed clean functioning SNES is cheaper than broken Sega Genesis lol). Therefore we can't know anything about "how much they go for", we don't even know what currency you guys are using so check it yourself on whatever 2nd-hand market websites in your country.
