You won't find any genuine dealers passing on coins that have previously been identified as copies, notwithstanding the permanent risk of a good one getting through. Dealers also tend not to list coins as unidentified. Particularly coins that verge on the iconic - this being the very first groat.

Here's another one - the classic 1562 sixpence. Reported for what it is worth.
This is the same 'coin' and seller as discussed last week, he is clearly a scum-bag and a fraudster with no scruples . Well done for standing up to him.

1993 1p with missing beads in places, odd striations where the beads should be and a rim that is uniformly ok in height. I'm certain it isn't post-mint.
'Unattributed' - the seller knows full well it has the WRL stamp, but is less than helpful !
