When introduced, loonie coins were made of aureate, a [[bronze]]–[[Electroplating|electroplated]] [[nickel]] combination. Beginning in 2007, some loonie blanks also began to be produced with a [[cyanide]]-free brass plating process. In the second quarter of 2012, the composition switched to multi-ply [[brass]]-plated [[steel]]. As a result, the weight dropped from 7.00 to 6.27 grams.<ref>{{cite web |url=http://www.gazette.gc.ca/rp-pr/p2/2012/2012-01-04/html/sor-dors324-eng.html |title=Order Amending Part 2 of the Schedule to the Royal Canadian Mint Act |work=Canada Gazette |publisher=Government of Canada |access-date=January 14, 2012 |archive-date=May 23, 2013 |archive-url=https://web.archive.org/web/20130523053520/http://www.gazette.gc.ca/rp-pr/p2/2012/2012-01-04/html/sor-dors324-eng.html |url-status=live }}</ref> This resulted in the 2012 loonie not being accepted in some vending machines.<ref>{{cite web |url=http://ca.news.yahoo.com/blogs/dailybrew/lighter-loonies-toonies-causing-headaches-vending-parking-machines-202448810.html |title=New lighter loonies, toonies causing headaches for vending and parking machines |date=April 26, 2012 |work=Yahoo News Canada |access-date=June 22, 2015 |archive-date=June 22, 2015 |archive-url=https://web.archive.org/web/20150622085456/https://ca.news.yahoo.com/blogs/dailybrew/lighter-loonies-toonies-causing-headaches-vending-parking-machines-202448810.html |url-status=live }}</ref> The Toronto Parking Authority estimated that at about $345 per machine, it would cost about $1 million to upgrade almost 3,000 machines to accept the new coins. The Mint stated that multi-ply plated steel technology, already used in Canada's smaller coinage, produces an electromagnetic signature that is harder to counterfeit than that of regular alloy coins; also, using steel provides cost savings and avoids fluctuations in price or supply of nickel.<ref name="gaz">{{cite news |url=https://montrealgazette.com/business/money/Material+change+store+loonies+toonies/5992375/story.html |title=Material change in store for loonies, toonies |newspaper=Montreal Gazette |agency=Postmedia News |date=January 14, 2012}}{{dead link|date=January 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
