Definitely a nice design.
A number of points to consider though.
If you're going for funded coins, then lower denominations may be more popular.
Having been said, given recent events, it may be more advisable to go with DIY coins unless you're prepared to somehow provide full transparency of your operations.
What he said. Just my own opinion a loaded 1btc coin right now might be a hard sell even with a full description of your operation which is also a tough sell now too. Good luck either way
