I got part of my first shipment today (ordered last Monday) which was a bit confusing. I only got $500 of coins! I checked the slip that came with the box and it tallied so nothing went MIA in the mail. I went online to see my order and all four presidents were shipped on the same day so I called the Mint and they said my order had been split into two parts.
As for the coins they are a bit disappointing IMO. Rather small and not weighty enough. If I didn't know better I'd guess they were tokens from a funfair! I feel I'd even have trouble using them out! If it wasn't for this thread I wouldn't have known about the existence of the things so I suspect many of the public wouldn't know either...
