if the photocopy shows your name as the owner, then you have no hassles to get a new original in case of loss. you just pay the Fees for that. if it shows a different name as the owner, then i hope for you that it is the exactly same written name as the name on your contract, the seller named in the contract, then also no problem to get a original in case of loss. if your car is brand new and from a dealer, hey, time to make some noise there to get your matricula done in your name and handed over to you, as thats usually part of the deal and already paid for by you when you purchased your car.
as Harley said above, the Original is yellowish.
if you only have that one copy which was attached to the 2013 receipt, do more copies. do Not give your dealer or anybody else your last copy.
in case you already did that mistake(no kidding, i did that once myself, original been lost in outer space), then you can request a copy from your insurance, as you had to leave a copy with them. thats how i did get a copy of mine again, and with that copy i got a new original.
