Just some info on the Silver Bank of Ireland tokens
In 1804 the bank of Ireland had quantities of Spanish and Spanish-American8 Reales or "dollars" restruck as Six Shilling Bank Tokens (the bank of England had similar coins struck into Five Shilling tokens as silver coinage was still at a premium in Ireland). Virtually no silver coinage had been struck at London in the period 1758 to 1804 except for the issue of sixpences and shillings in 1787 and the "Northumberland" shillings of 1763 when the Earl of Northumberland took over as Lord Lieutenant of Ireland and distributed a 100 pounds worth of these silver tokens.
the Bank of Ireland issues are:
6 Shillings - 1804
30 pence (or 2 shillings and 6 pence) - 1808
10 pence - 1805, 1806 - type 1 - inscription is across the field on the reverse
10 pence - 1813 - type 2 - inscription in a wreath on the reverse
5 pence - 1805 and 1806
There were a lot of contemporary forgeries made (mostly in Birmingham) - basically they copied the coinage in base metal and then silvered them over.
There are proof strikes of these tokens and I have also seen counterstamped examples. The Royal Australian Mint has specimen copies on display
Hope this information is handy - source was Coins of Scotland Ireland and the Islands (Jersey, Guernsey, Man & Lundy - Standard Catalogue of British Coins Volume 2 by Peter Seaby and P. Frank Purvey. Mines an old copy from 1984 but I find it a very handy reference (plus it's a 1st Edition)
Happy New Year to you all and good coin hunting
