As far as the coin number is concerned: No, it is not a returned coin (I have not had a coin returned yet). The reason why it is lower than you probably expected, is because I had it packed and ready to be shipped to a customer. However, the customer wound up never paying through Coinbase and decided that he no longer wanted to go through with the order. So, the coin was packed away for more than a week, while other, higher number coins, were being shipped. You happened to be the next shipment when I found out the customer was no longer interested.
And as for the scratches on the back of the coin: I'm assuming the scratches are on the inset portion of the back that will be covered by the hologram. Unfortunately, the majority of the coins have some flaws on this portion of the coin, and I am attributing it to the fact that it is a very deep inset. I deemed that to be acceptable, since the intention is to have that portion of the coin covered with the labels/hologram. Also, these are not proof or proof-like coins, and I am told that a proof-like quality brass alloy is not really option for any mint, despite what they may say in their sales brochure. In the future, I hope to rectify this by using silver or gold plating on any brass alloy coins.
If you want, I will gladly refund you the cost of the kit, and you can keep the coin. Or, I can send another coin out, at no cost to you (keeping in mind that there are flaws on the inset portion of most of the coins). Just let me know and thanks for the feedback.
About the scratches, yes they are on the back of the coin, right where you said that they most likely will be. You are now forcing me to make a though decision. I mean, you already gave me a discount (which I still appreciate) and I don't want to rip you off. But having a scratched coin is something I dislike. Decisions, decisions.
