Hi there, I was searching through my coins and noticed that a lot of the 50 cent coins have the same partial collar errors,(being a thick collar on the left and thinner on the right, as hopefully shown in the picture. Is this simply common, or is it coincidence? Are these coins worth collecting? Thanks :)   Edited by Ingine

Partial collar errors are basically coins that have been stamped off centre, sometimes called misstrike errors this is the most common type of error coin that people will find in there change.
Some people like collecting error coins; this coin is a common example and would be worth $1
Hope this helps you :)

Your coin was struck with misaligned dies(MAD), it has nothing to do with the collar. MADs occur when the hammer and anvil die are slightly out of alignment with each other, giving one side a slightly uncentered appearance. It is generally an acceptable part of the minting process unless the misalignment is so severe that some of the peripheral devices are missing. The collar, aka the third die, defines the diameter of a coin and creates reeding for appropriate coins. If the collar is not fully engaged when a coin is struck, the planchet will squeeze out between the dies and create an area with a larger than normal diameter. Pictured below is a US Kennedy half dollar struck with a tilted partial collar. The area on the left is where the planchet expanded beyond the collar.  Edited by biokemist6

Thanks for the feedback & for the welcome :) Since I have so many of these error coins I will assume they would not be worth much. I do love my error coins though so will keep them all the same.
P.S. I love this site - so many knowledgable & friendly people and so many awesome coins to look at, Thanks!

I am the same, I will collect them all up and keep the better ones in my albums.
Always swapping them to a new one I find!

Your 50c is not an error, just a variation in alignment of dies as suggested by biokemist6. It is worth 50c and you'll find if you look at all the coins in your change that most of them are ever so slightly off centre one way or another. Quote:

Hope this helps you :) Australian Coin you should really do a bit more reading before you post up this sort of stuff. Partial collar errors have nothing to do with being off centre, nor are they the most common type of error coin found in change. The coin shown by the OP is not a partial collar error and it's worth 50c. Try reading biokemist6's post, buy a book, or do some more research. For your reference here's an Australian partial collar error:  Edited by markn

Thanks Markn - I will do more research before posting. Like you said - most coins I look at are slightly off centre. I do however appreciate people's different views & opinions. Such a wonderful site!

Ingine there were a lot of 50c in that era struck a bit offset
I don't consider them as collectable varieties
Good post

ingine please ask whenever you like. The only dumb question is the one not asked. I have found that to ask a question always gives you an answer. There are a lot of very knowledgeable people on this forum that are very willing to answer your questions BTW  |
