Mint Rolls Vs Mint Sets

Thanks, that's what I was thinking, especially in the 2005-2010 range. I'm looking to pick up some single coins on ebay to fill holes. For those years though it looks like it should be passing up listings coming from mint rolls and sticking with ones in the cello's for a better quality coin.

The coins from the Royal Australian Mint in Canberra, that are to be issued for circulation, are just spewed out of the coining presses and drop onto a pile, on top of each other.
They are weighed and bagged and kept until issued to banks.
I have yet to see a freshly minted coin straight from the issue bank, without at least a few bag marks.

Coins for mint sets are struck in exactly the same way, but are extracted from the coining press individually, and are packaged into blister pack sets. They escape brutal machine handling, and thus are not bag marked.
Rolls are sometimes produced and marketed for collectors, using these coins.
I suspect that selected normal production planchets may be used, and the dies are normal production dies, selected for mint set production. The coins, nominally, are perfect.

Mint Set coins are special. The satin finish may be gone, but they still receive special handling.

As far as I know, Mill Roll coins come from the normal circulation strikes.

What Jbuck said that cladking said. The mint set coins ARE different in that they are produced to get the best possible strike for a "business strike" type of coin they can. The ones in the mint rolls are normally produced and handled. This is why most of the circulation coins you see graded MS 68 and up are mainly from mint sets.
