Timeline Originals and its Certificate of Authenticity

Coiney Cliff Laubstein notes that Timelineoriginals is an "honest & respected dealer" and also notes that as guarantee of this is that it is a

member of the British Numismatic Trade Association, American Numismatic Society, Trustworthy & Transparent Trading, American Numismatric Association, & Ancient Coin Collectors Guild

but nevertheless, despite all these alleged "safeguards"

has this well known eastern european cast fake crap Lysimachos Tetradrachm for sale, Buy It Now for a mere $678 including an "Illustrated Certificate of Authenticity".

He suggests the Timeline coin (the same coin on their website) should be compared to two exactly the same, with the same defects as well, on the coin forgery network, here and here. He adds that he is sure this is an "honest mistake", though how honest is it to issue a certificate of authenticity for an object you cannot say where it came from and when you do not have the expertise to spot what Laubstein says is a "well known east European" fake, and one which is cast and not struck? In fact there are a number of issues with where precisely a number of items being sold by this dealer are coming from, some of which have previously been mentioned on this blog.
