I think the 50 gold price tag is a little much. What happens when someone has a typo? You've either got to live with it or flush another 50 gold down the drain.
Very simple solution: Don't make typos.
When you are spending 50 gold, is it too much to ask that you double-check your spelling? When you, say, found a company and make a typo in the company name, it's also pretty expensive to change it later on.
