Well the marketcap would have to rise to $1 billion for the coin price to be $1. And it would be 2nd to bitcoin. That's going to take a little bit of time. Lol.
The reason some coins start at a higher price has to do with a lot of variables. This coin has a billion coins in total so the price should be relatively low compared to other coins with a small supply. But the amount of capital raised and the development team are going to affect that price as well. The amount of marketing done beforehand can really pump up the perceived value, look at Ethereum.
