I bought three miss-struck coins at a local table top antiques fair on Friday.

Hussulo

The first two are clipped planchets:



I liked this one because the clip is almost exactly at six o'clock.

Some people try and collect what is called a clock collection of clipped planchets for the same type of coin. I.e one with a clip at 12 o'clock, then 1 o'clock, 2 o'clock etc. Until you have an example of all 12.

I might try that some day.



The next coin has me a bit puzzled I have to weigh it but, even though thir are a few scatches on the reverse, I don't think it's been filed down. If it hasn't been filed, then it isn't like any error I know of, as all would leave some impression. The only way it could have been made would be with the use of one (obverse) die.



I better weigh it before I get to exited though.

I took the coin out of the 2x2 and weighed it. It weighs 10.74 grams on my scales.

According to the books it should weigh 11.3 grams, but I weighed 2 other 10p coins of the same type on my scales and one weighed 11.23 and the other 11.19.

The edge is also plain and it is the same size as a normal coin:

That difference in mass is more than enough to account for the coin having been skimmed and the reverse design removed.

The clips look nice, but I dont see any evidence of the Blakesley Effect on either of them. Does anyone know if UK coins have their rims formed in a separate rimming process?

Hussulo

You are correct.

I have had a look under magnification and there are faint signs of reading to the edge so I am sure it is post mint.

As for the Blakesley Effect, as far as I know although a good indication it doesn't always appear in all clipped planchet errors.

CIVITAS

I think I see some Blakesley effect above DEF. on the 6d.

I have doubts about the 2d.

mnemtsas2

I may see some weakness near the DEF on the 6d but I see nothing on the 2d. Another indicator of a genuine clip can be fish tailing of design elements near the clip, so rim beads can be elongated and normally flat bases of lettering can be curved. It see some indication of this on the 6d (note how weak the beads are around the clip), but very little of it on the 2d. I am not sure the 2d is genuine.

Hus,
The 2p. & 6d. coins are genuine errors,as they are struck on planchets that were cut too close by mistake.

That 5p. coin is definitely a dud.You be better off cashing that in at the Bank of England in Threadneedle St.,London,& get your 5p. back.

Aidan.
