Hiya. That Wilkinson token is really nice. 1788 has a barge on the reverse. Some have a man operating a forge with his back really close to a furnace. Others have Vulcan (as per your illustration). Some are payable in Anglesey London and Liverpool. Mid-spelling of Wilkinson is quite common, usually on contemporary counterfeits, which are usually light and poorly struck. A reversed N in Anglesey and London is also quite common. Bronzed and silver proofs also turn up.
