The old £1 coin was the 1983 replacement for the Bank of England £1 note. The note remained in circulation alongside the new coin until 1988. The old £1 coin reverses featured many different designs. Designs alternated each year for the UK, Scotland, Wales, Northern Ireland and England. None are actually commemorative designs.
There were lots of fake old style £1 coins in circulation. They were of lower quality than the real ones and very often have mis-matching reverse themes and edge inscriptions. (Compared to how they should be for the date shown on the heads side).
Edge lettering up the wrong way?: Lots of recent enquiries about the wording on the edges of £1 and £2 coins. The edge lettering can be up one way or the other, it’s completely random. A tabloid started an unfounded rumour in December 2016.
There were 46 different ROUND £1 coins. 5 of them were available in sets only, these were 1998, 1999, 2015 shield, 2016 shield and the 2016 last round pound.
Two 12-sided £1 coins have officially been released (one dated 2016 and one dated 2017). More information on new £1 varieties here.
