To make unloaded coins is quite straightforward, or to sell small denominations of loaded coins is fairly simple. Making 1btc coins or higher value coins (we make 10btc & 20 btc coins) is a little trickier given need to comply with various regulations (which vary depending on which country you are selling to/ where you are based).
If I were coming out with a coin I'd be pretty wary of selling loaded ones. People do seem to be weirdly accepting of total strangers creating their private keys in coin form but I would've thought it would be a tricky sell unless you've earned a good rep already.
