idk mens, they are not the same skins (the thing at the end is different), on one of them there is like a face and on the other one there is not, prob there is just less of one of them but I'm not that good at skins etc.
No they don't. One has a face on it's handle & another one don't. The first means "one" and second means "two" in jalapeno. As for the price, no significant reasons on why the huge gap but maybe can be put as limitative in quantity or having the face one being much more unique.
They are similar and technically they have the same value as they are equally rare.
If you do a trade up, you have equal chance to get any of those. They are equally rare.
It's the no. Of skins on the market that decide the price.
Since there are a only few, people tend to put them on higher price than they should be for to get extra money.
