Valuable Fake Coin at Auction

At an Auction that Runs on the Internet Recently not I found a 1847 Gothic Crown with the Description ( 1847 Silver Queen Victoria Crown) and as I collect Victorian Silver had a look at it but found there was something just not right with it and on closer inspection it was definitely not a Genuine Crown what do you do in these Circumstances Contact the Auction House or Say Nothing. I contacted the Auction House and the Lot was Withdrawn with a thank you from them I am just Wondering how often this Problem arises and has anybody Bid in good Faith and when Receiving there Coin/Coins they are found not to be the Genuine Artical.

The Fake is No1 The True Gothic Crown is No2.

At least you didn't buy it first, then discover it too late like I did with this one at a "legitimate" auction...

As far as I know auction houses are liable for the correctness of their sales not like those ebayers with their "no guarantee of authenticity" line.

Yes I think that is true and the reason it was Withdrawn from the Auction 1 Day before the Sale I just wonder who there Coin Expert is as Auction Houses who Auction Coins should hopefully have someone who knows what to look for or can call on someone who Does.

usually they do have one or two real persons who will attest, and be held to account in cases like this.
I have experienced failures in very good houses, it can happen, but they strive to improve, so bear up.
