The man looked at Leo weirdly for some seconds and Leo was sure that if things were not as crowd and chaotic as it is right now, this man wouldn't hesitate to rob him of his coins.
The fact that he brought out a gold coin made the man think that he has more and sure enough, the man could not help but be greedy for more, but luckily for him, he held himself from taking trying to steal from Leo, because if he tried that, he would be dead meat.
Leo also found out that people couldn't see his ring, not even cultivators! Just as it concealed its presence from him did it do to the others, but unlike him, they couldn't see it at all.
So to bring out a coin, what he did was simply put his hands into his pockets, and then summoned one gold coin from the pouches he stored in the ring, and it's done!
