2014 AIATSIS 50 CENT COIN X 20 mint bag http://www.ebay.com.au/itm/141827419815?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT good value
The roll with the letters fifty cents on the paper is released from RAM, and the roll with the plan wrapping is a bank roll.
Thanks for the reply chrisee I picked up 2 rolls with no writing on eBay for $27ea. Didn't notice they where bank not ram rolls until later on
That plain roll may be "home made". Normally bank rolls are from security companies who generally have their name on the roll. e.g. Armaguard (logo) / Prosegor Compare the neat end in the RAM roll to the the folds of the plain one. Big difference in the rolling there!
I got three rolls a while back, they gave an estimated mintage of 2 million at the time but I guess three million isn't that bad either.
All the 50 cent mintages are listed here: http://ramint.gov.au/designs/ram-designs/50c.cfm Couple of 1m years and many in the 2m zone. The only 50 cent coin I collect is 1966!
