Here's an engraving mistake I made a few years ago. I engraved about a half-dozen of these charms for a lady, and each one had a grandchild's first name on the front side and birth date on the back. She emailed me and said that one of the charms (this one) was engraved with the name going bottom-to-top as opposed to the others which went top-to-bottom. Well, there was no fixing this one, so I had to buy a piece of gold and saw out a new charm and engrave it, losing any profit I might have made! Oh well...a lesson learned. At least I have a piece of scrap gold
