Hey pubcrawler, Those are some fantastic pictures. Actually I see World Error coins for sale pretty often.
Yes, I was speaking of eBay, in particular. I don't recommend the venue to others, but I do use it myself.
Let's put it this way - world coin errors are noticed - but certainly not to the degree that US errors are. And very seldom do world errors bring any kind of a premium. For the most part - they are ignored. Before the modern age of minting coins - let's say before the 1970's - errors were far more common worldwide. But with the advent of new minting technologies errors bagan to be found less and less. It has only been in the past few decades that errors have become popular at all. But today error collectors abound. The primary market is for US coins - but this is no different than it is for any coin. US coins bring much, much higher prices than comparable world coinage. This is true for not only errors but varieties and ordinary coins as well. In the 19th and earlier centuries it far more likely that you would find a coin with an error than it was one without an error. This is true for all coinage. As a result - coin errors from these time periods are simply ignored.
Nice find! Were it me, given that the piece will probably not command a substantial premium, I would hold onto it as a very nice example of a doubled die.
