Halfpenny, 1775, overstamp

[Guest richbedforduk]

I don't know where to start!

I thought that 'milled' coins were milled. Then later they stamped and pressed them. But this looks like it was pressed.

Would someone kindly educate me (non-technical wording) please.

Trying Hard

What you have thre Rich is a doublestruck error.

Doublestruck coins take place when after a coin receives its first centred strike it fails to

be ejected from the machine and is re-struck again. Coins can be found that have been

struck three or four times. Doublestruck coins where the date/s are still visable and the

second off-centers strike is at least 10% off-centre are more collectable and valuable.

Edited to add:

Hand struck coins were struck by hand using the strikers own human force. The coin was stuck onto a flan which was hand cut using a pair of dies and a type of hammer. Each and every one is unique and individual.

Milled coins use machine power to strike the coins.

The planchets are stamped out of a rolled sheet of metal. The coin planchet is then fed into a collar (a device which surrounds the edge of the planchet as the coin is struck). The collar keeps the coin metal from spreading larger than its intended diameter. The collar die also imprints the edge design, if any, onto the struck coin. The obverse and reverse dies then strike this planchet to produce the desired design of coin.

Thank you for that.

It's quite awesome to think that 232 years ago this coin, with thousands of others, was being hammered out in a noisy factory and got screwed up. (I wonder if the guys got penalised for getting it wrong?) It then obviously bought a few beers and ended up here.
