I have been reading a lot about provenance lately on here, and it has brought up a few questions/ thoughts. I understand the general importance of knowing the history of a coin, especially rarer varieties. and i have seen a few of the guys on here say that a coin is ex "smith" collection and before that ex"jones" But what about the more common coins? eg; I have a EF double florin that came from a local dealer, who got it from an auction but that is it ( i could dig out the records to go further i suppose) and for others might just be EF examples from pocket change I assume that recording provenance is personal preference for the more common coins I suppose my question is, if at all what do you do when it comes to recording provenance? and what makes/ inspires you to do so?
