General Varieties/Errors

Varieties - this is where they use a different die for the same coin so there is a slight difference in the design.
Cud- this is where a piece breaks off a die and the metal flows into the hole that was left from the chip.
Rim cud- same as a cud except it happens on the rim of the coin so there's a raised up section.
Die crack- this is where the die gets a crack and the metal flows into the crack leaving a slightly raised section but must be raised off the surface of the coin.
Rotation- this is where one of the dies rotates around so the obverse and the reverse do not line up properly.
Lamination- this is where there is a fault in the planchet (the blank coin) and it looks like the coins is split or has a flaking appearance.
Partial Collar Errors - coins where the collar has not engaged properly and the coin has a "railroad" rim
Broadstrikes - coin struck out of collar and out of alignment but all the design is present
Off-Center Strikes - coins struck out of collar and out of alignment but some of the design is missing

I bought quite a few 1985 mint sets last year so It might be worth breaking out some coins to get slabbed at some stage

Rotated 2001 CoF $1  
Rotated 1996 Parkes $1  
Rotated 2010 50 Cent

All of the various 'collar' error types that can occur.

My daughter and ex was given a very worn sovereign as a 5c piece at a service station many moons ago.

Other than those above already mentioned, some NCLT 50c pieces, IE   Melbourne Cup 150 years, Ballet coins.

You find that AJ?

[ausjack]

Yes a few years ago and would love to find more but a bit rare to find but well worth keeping an eye out for anything out of the ordinary.

I have compiled everything into the first post and where possible linked to either the Wiki (first choice) or the Australian coin blog.  Can someone expand on why some of the circulation coins (1985 50c for example) are worth more?  Also, what about strike throughs, split planchets, clamshells, and rim clips?  Are they ever found in circulation?  What about rabbit ear dollars, are they worth more?

[Goldseeker]

Rabbit ears and Spew Roo dollars are worth what someone is willing pay.   The coins themselves are still only worth $1 but if several people want an example then that is where the extra dollars come in.

Simply put it is all dependant of supply and demand.

Just my thoughts.

the 85 50c, although people say is a low mintage, I have "we my family" came across a few in change, you prob don't come across them as often as when we first started, and I guess as more people look for them the harder it will get, {supply and demand}
error coins come mainly from production, so with a machine that pumps out a few hundred in a minute, you cant guarantee, that its going to do every coin exactly the same every time, a coin may be flicked in the stamping mechanism the wrong way, the wrong timing, or a die might start to wear out or develop faults - all part of the manufacturing process
then the coin planchet (coin blank) - (before being stamped with the design) itself may have flaw too, like the wrong metal mixture or a air bubble under the surface, when struck would cause a lamination effect, split planchet
