Maybe someone who actually has a catalog will see this post
Well my Seaby is from 1984 and I would agree that it is attributed as #5432. The description is "Crowned thistle dividing MR" and "Plain saltire cross through crown, cinquefoil each side, OPPIDVM EDINBVRGI". A subtype with a voided cross is #5433, but that is not what you have. I agree that your coin does not have these six-sided stars on either side of the crown and I'm not sure what to make of this omission.
Here is a link to a Bawbee in inferior condition, but with the cinquefoils:http://www.londoncoins.co.uk/?page=...searchtype=2
I'd estimate that somewhere in the range of $95 to $150 is a reasonable value--maybe a smidge more because it is entombed.
