I was looking around and saw this pretty interesting coin http://www.ebay.com/itm/2011-SOUTH-...880805?hash=item3f72cb87a5:g:dzMAAOSw8w1X3rTl To my understanding of the definition of overstrike, an older coin is used as a planchet which the original host design often get destroyed with the newer design. Often this leads to a messed up looking coin. This to me is more of a counter stamp or a privy mark. Your opinion?
The reverse does not show evidence that the mark was made after the coin shaped object was struck. I think it's a privy mark added to the die for promotional purpose.
As such, I'm certain this cannot be an overstrike. I wonder if NGC will recall this slab and correct this mistake. Grading can be subjective but terminology? Come on...
Sometimes only the dies were changed into something else, for instance changing the date from 1815 to 1816 or something like that. I dont know how they call this in the States? Do you also call this an overstrike? Kees
No, when the date is all that is changed it's usually referred to as an over-date. They merely use a punch and and punch the new date into the die right over top the old date. They also do similar things to mint marks and those are called RPM's - Re-punched Mint Marks.
Ehhh, maybe. Typically a privy mark is only used to refer to a specific person like the mintmaster or the assayer. But sometimes they were used to identify a place, a location. But one thing's for certain, it's not an over-strike.
Thanks! That is much clearer than here in the Netherlands. Here an over-date is called an overstrike and an old coin totally overstruck with other dies is also called an overstrike. This is very confusing, especially for beginning collectors. Kees
Well, maybe that'll change in the future. There's a book out there that I helped write that explains a great deal about the minting process, specifically in the Netherlands. This is it -
Yes i know the book! I know Dariusz also and see him sometimes at coin shows here in the Netherlands. He gave me the book as a present because i helped him with literature, books, translations of old Dutch texts etc. etc. Kees
Ahhhh well, someone else who knows Darek - 'tis a small world. But you being from the Netherlands and interested in coins, it stands to reason. His name has become widely recognized over there, all over Europe actually. And I'm doing what I can to make that so here in the US as well. Get him to tell you the story of how he got started, how he met and got to know me. I'm sure you'll find it interesting, and perhaps even a bit humorous I've spent thousands upon thousands of hours teaching Darek and helping him with his studies. And writing the book of course. I think of Darek as a son. But now, his knowledge of Netherlands ducats far surpasses that of mine, and pretty much anybody else in the world ! But once the books are all written, that knowledge will be shared with the world, which has been my goal since I met him.
I will ask him about how you two have met. And his book is indeed well received here in the Netherlands and amongst collectors of ducats all over Europe. But i think we are completely off topic now. Sorry for that gxseries! Kees
I don't know the specifics of this coin but i believe that if the the Australian Mine monetized this as an Australian piece then that could indeed be looked at as an overstrike.
