A Russian man from Yekaterinburg became pretty popular on Instagram for his coin and Zippo lighter engravings. He has already got over 70,000 followers and all the art he makes he is selling.
He says he never designates a price for his art.
He starts with a $0.99 starting price on eBay (the only platform he uses to sell his things) and posts a link into his Instagram account.
Later he says “buyers decide what would be the price themselves by bidding, I never know the final price of my art”.
Here are some more of his creations as well as an animated gif of some of those:

Here is how he is doing those:
Looks like all he uses is a small screw driver?
