FAQ
Frequently Asked Questions
No. While historically it had an obsolete meaning of becoming out of date, its only current standard meaning is the technical one of altering a date on a coin or document.
'Overdate' specifically implies engraving or stamping a new date over an old one, often fraudulently. 'Postdate' simply means to write a future date on something (like a cheque) and is not inherently fraudulent.
Yes, to collectors. An overdate is a recognized minting error or variation, and certain overdates are rare and highly sought after, increasing a coin's value significantly.
Usually through careful visual inspection, often with a magnifying glass or microscope, looking for traces of the underlying date's digits or inconsistencies in the metal flow around the date.
