A large portion of my order was duplicate coins, but only one had a double fund.
How do you know that any other part of your order were duplicates?
I think it is because Smoothie told him:
Apart from the double funded coin, were there any single funded duplicates?
If so, how do you know that they were duplicates?
There were, and I didn't know they were until smoothie told me they were. There was no real way to tell the single funded coins were duplicates.
Ahhh, gotcha.
If I had to guess, I would speculate that smoothie creates his coins, generates the vanity address/private key pairs, the associated sticker, places the sticker on the hologram, destroys any remaining copies of the private keys and places the hologram on the coins ahead of selling his coins. In other words, the coins are 100% ready to ship, provided he has access to them (he likely has them locked up somewhere and does not have easy access to his inventory). This would at least make the most sense from a production standpoint.
If there was a printer jam when he was printing the stickers for the coins that you purchased, after the jam is cleared, printers will sometimes print one page that was already correctly printed. It is possible that the sticker that your private keys were printed on were printed immidiately prior to smoothie's printer having a printer jam, resulting in the same private keys/first bits being printed twice.
The above is of course speculation. I have purchased many Lealana coins directly from smoothie multiple times without incident, with smoothie always being very professional when trading. I personally think that smoothie is safe to trust and that smoothie's coins are desirable, and safe to store BTC on.
. I think it would be in his best interest to reply in here as soon as possible to bring some clarification to this whole thing.
