First your not suppose to remove the tag nor alter the attaching hardware.
As for what the rivets are made of test them first with a magnet. Think they might be steel but don't have pictures nor recall seeing rusty ones.
The ones used for your year and plant appear to be standard rivets like what you can find at the local hardware store
Well thats a bummer! That is what I checked here first before I removed the VIN, otherwise I would not have removed it! See below

Just checking to confirm if these rivets look original. One looks older and one look fresher. Not sure what the originals should look like, but thought I should ask before assuming. FYI I am thinking of doing some media blasting and will not remove the vin if it looks like the rivets are original. If they are original I will tape it up well.
Thanks
The rivets holding the vin tag on were nothing special. Yes in your case one seems to have a different patina then the other. Take them off or leave them on. I personally would not want to run the risk of the vin tag getting damaged . Since you can't tell the different once reinstalled you are not losing anything by removing and re installing. In your case at least two different ones will most likely match each other better. Some people are funny about drilling out those common pop rivets as if it is desecrating the car in some way. To each their own. Regardless you have a choice.
