The document did not indicate what sort of coins were involved, and a service spokeswoman said details of the incidents were classified.
Intelligence experts surmised the miniature transmitters in the supposedly rigged coins might be used to track the movements of defence industry personnel.
Knowing their whereabouts could help determine who they were meeting and possibly reveal dealings with suspect countries.
In a statement posted late Friday on its website, the Defense Security Service said the coin claims were based on a report provided to the agency.
"The allegations, however, were found later to be unsubstantiated following an investigation into the matter," the statement said, adding that "the 2006 annual report should not have contained this information."

Always blame somebody else.
No comment from the Canadian Mint yet? Or from CSIS?
I guess the rumour was too ridiculous to be taken seriously.
Now if these were reportedly found in US coins, I could believe it. "Imbedded".
