1826 George IV Shilling, Strike Error ?

I wasn't around till after decimalisation either UKPH, but the old coins circulated alongside the new ones until they downsized them all in the 90's.

If you were a child of the 90's though there isn't a lot of fun stuff you can pick out of your change.

Side note - I realise now that the date is weak not because it is on the other side of the error but because where they soldered they polished and cleaned up the solder join.

I agree 110% that adding a loop or pin is nothing short of abuse to the coin, oh those Victorian era memento/ keepsake emo's



Another 1826 shilling, this time turned into a brooch

The coin is solid sterling. If it was plated after it left the mint, the plating would never be that thick and would not explain how the details are sharper at the high points where it presumably would have received a thicker cladding. I don't think there's any doubt at this point that the coin exhibits a lamination error.

Yes, laminations are caused by impurities in the metal.

I agree that the wear certainly makes error coins like this more difficult to identify.
