For example, the 1804 dollar or 1964 silver coinage struck after 1964. Are those actually restrikes? Is there just a grey area for restrikes regarding whether or not they are considered original (or pseudo-original)? Does it matter if the coin in question was demonetized at the time it was restruck? I'm encountering this problem for my sets, where a government controlled entity for Hungary produced restrikes for the collector market, but also sold older original coins. When selling older mint sets, they sometimes substituted - let's call them replacement coins - when originals were not available. These are essentially unmarked "restrikes" made with original dies by a government entity, sold as originals, and the "restrikes" were not otherwise made available outside of these "original" sets. What are they? Restrikes? Originals? Something else entirely?
