1942 Half Penny (Melbourne) ...errors?

Hi Kafka,

Sorry mate, but to me neither actually look like errors, rather affects that have occurred post manufacture through circulation / wear / storage. (IMO).

Your first coin seems to have what looks like a patch of deterioration or stain, perhaps from previous grott build up, or similar? (I think this is what you are identifying when you say 'something wrong with the planchet')?

The second does have a dot, in fact there are a few if you look closely - the coin also appears to have some milder deterioration and pitting, which may have caused the dot? (chemical reaction of metal with ? resulting in raised area, or similar). Hard to really tell without looking at it in the hand. Might actually be dots from manufacture - unsure.

Either way, if they are errors, these sorts of error seem to have only a little impact (in general) on value in early PD coins (die cracks, dot errors, lamination flaws, rotations, etc). As I say though, they look more like detractors to me, particularly given the state of wear and other marks / detractors visible.

If they were errors, their impact on value would be significantly outweighed by the negative impact on value of the other detractors visible in these coins.

Just my opinion, based on images provided - hope it helps.
