I have two of those Silver Slipper halves. One in my collection and one was a trader. After Bob (thanks Bob) posted his reply, I checked my collector. It has perfect medal alignment! A Borland knock-off. The trader on the other-hand is off. Not enough to not be a Borland knock-off, but certainly possible to be a real one. Anyway, I no longer have a trader.

Thanks for your question.
