This is good news. In a few days you should be able to track it on the USPS site. You can even sign up for email alerts as it travels through the system.
Something similar happened to me a few years ago (different company, though). It took some time for them to get the coins out, i think at least a month until shipped. If not mistaken, the company I was dealing with was in Spain. Also, I saw an earlier post mentioning Russia- transit times are usually terribly long in the several instances when I have had coins coming from Russia. Am guessing due to items having to travel through many regional post offices as to the reason.
@Bayern: Thank you. Yes the Katz Auction house did state that a coin or coins had to come from their Moscow office. I did not know this at the time of bidding. I do have the tracking number of the package. Once I receive it I will let this thread know.
I would not recommend Katz Auctions, due to different problems (customer service, consignments...) In other forums there are more affected by this auction house.
Once Again Thank you to every one who contributed to this thread. The coins arrived in today's mail from Katz Auction House. To be fair the post from Prague took nearly a week. In total, it has been just over a month between being notified I won the lots and my immediate payment to today's mail. Katz Auctions does offer some nice coins to bid on. I just have to reconsider the amount of time it took to obtain the coins.
