Here's a 3 Ringgit postal order from Sarawak.

It is the first numismatic item that I have scanned since upgrading to Windows 7 & Internet Explorer 9 from Windows XP & Internet Explorer 8.

Please let me know what you think.

These scans are very  nice, Aidan, though I personally have little  interest in the item itself.

Perhaps your coin images will be better.  Your currency scans seemed good before , too, but your coin images suffered.

I would suggest finding thin film, like a glassine envelope and use one thickness/layer only, to protect your scanners glass.

Coins are abrasive to scanner glass and the glass is not good foe coins either. 
Rotating a coin on a scanner glass can cause wear, in the form of polished areas on high points.

Larry,
  I have no idea where to get glassine from,as I think no-one over here in New Zealand sells it anymore.

If they did,it would be quite expensive.

My banknote & postal order photos are O.K..

I know about my coin photos being not so good.

You're right about wanting to protect the scanner's glass plate.

Aidan.
