If you have any interest in History you have seen for sale at places like ebay Roman coins and other ancient treasures in many other varieties. If you haven’t just type Roman Coins in the search and you will see hundreds on sale in various conditions.
In some cases these are fakes seeking to dupe the unsuspecting. A few years ago I bought a signed Bobby Thompson baseball which I am still not convinced is real, though the novelty of having a possible signed ball by the player who hit the “Shot heard round the world” makes it fun to have.
So if you bought a fake, sorry, it is ebay after all so you take your chances. Much like our purchase of Sailor Moon Dvds for our daughter which obvious came from Chinese knockoffs. The first big clue was on the packaging it was called Sail Or Moon… yeah that is sooo official.
While you might be miffed I am somewhat gladdened if you got a fake. It means you are not supporting those who are selling history online for a few dollars. While Roman coins are plentiful in many areas of Europe they can still be significant and important if they are in the ground. In archaeology this is called stratification. This means that the layers of soil can tell a story of the area. Much like tree rings soil can be found layered and each layer can represent a specific period in time.
When items like coins, broaches, clips, arrow heads or anything like it is moved it destroys the story associated with that object.
