Foreign RCM Coins With Laser Engraved Security Feature

Is it worth the expense of providing a secutity feature on a low face value coin?

This debate has to be taken with high the denomination One Pound coin in the United Kingdom.
Bi metallics is one approach to this problem.
Engrailled edging is another way of achieving this.

The approach (as seen here) is to make a sufficiently small and deep indent into a coin, where the high definition detail beyond the ability of striking, is protected within the deep indentation. Such a process can be industrially reproduced, but high capital expense equipment needed to do so, would be required to reproduce it in volume.

Individual diamonds are 'fingeprinted' with a tiny laser engraved serial number in the girdle of the stone. My problem with this, is that cubic zirconia stones can also be laser etched in the same way. Nevertheless, would you bother doing this with a $2 coin?

If you have a friend in Winnipeg, ask them to photo the flags on the mints driveway, you will know which countries the RCM is minting for, they are very secret about this type of info, but also very stupid.

Multi ply technology is an excellent idea to thwart counterfeiters. Any large denomination coin is at risk to counterfeiting. British 1 pound and Australian 2 dollar coins are good example of this. While counterfeit Australian 2 dollar coins are not too common, the British 1 pound coins apparently is quite bad. I'm all for newer technology as long as the cost is reasonably achievable and it keeps the counterfeiters away.

As for the list of countries that the RCM has contracted to strike such coins, this might be one interesting pdf, page 3

I believe the list of countries have gone up to 35. I'm sure with a bit of searching, you can find everything on the RCM website. It should be in the annual financial report.
