Project to list known Error coins

By on 9th August 2018

It’s about time someone compiled a list of known UK decimal error coins and I need your help to point out coins that I may have missed or simply don’t know about yet.

Due to their random nature and the probably never ending task of listing and describing them all, I’m not really interested in:

Clipped planchet errors or damaged planchets (including lamination errors).
Blank planchets, unless they can be attributed to a exact coin type and date.
Die cracks, chips or cuds, unless they are very distinctive and are already collected varieties, e.g. the digit ‘1’ on some 2008 20p’s, cat on mast on the 2015 Navy £2 etc.

I am very interested in listing the following:

See my Error coins, an Introduction post which lists many types of errors numbered from 1 to 27 , the kinds of things I’m most interested in listing are…

Well known die chips and distinctive cuds (some of no.1), partial collar errors (no.5A), broadstrikes (no.5B), known die clash errors (no.7), coins struck with a rotated die (no.17), doubled details but not bounced strike or die-wear related (some of no.18), mis-alligned centre pills (no.20), brockages and die caps (no.22), mules (no.24), off-centre strikes (no.25), wrong planchets including incorrect mono planchets for bi-metallic coins (no.26) and mixed denomination coins (no.27).

Info and good quality pictures are welcome to info@checkyourchange.co.uk

So far I have produced this table containing over 200 error coins, currently pictures are not provided.
