Something very similar happened to me! A long time ago a friend bought a museum copy of a Tudor sixpence, which I thought was amazing...until I acquired a REAL one for less than he paid for his copy...cue a life-long passion for coins!You can own hammered coins for under £20 a piece, easily! How much you want to spend, and the quality you will thereafter seek out, is all part of the journey! I'm afraid I was taken in as a dealer - someone offered a Roman coin and an Elizabeth 3d for which I offered £20 (being unsure about them). I sold the 3d but the purchaser was later unhappy about its thickness (too thick) and it turned out to be a replica. Cue refund of selling price and hasty withdrawal of Roman bronze from sale. Lucky I'd only paid £20, and recouped half of that by selling them as replicas. It only goes to show though ... KNOW YOUR SUBJECT!!! (The person I'd bought them from was obviously trying it on with things he'd bought from a Museum shop - I never met him in person, he just left them with the owners of the Antiques Centre so I could make an offer).
