how can i clear that secret Veneer Hi
my friend gave me a mysterious 10 dollars and on the back of it there's a secret code hidden but theres something weird on it covering it what i don't know how to erase it. This is the picture i feel like its thicker than an actual dollar this is all i know.
Could anyone help me solve the problem ? How and with what can i erase it?
Use household tools!


Can you bend or fold the note? Is the layer brittle and does break off?
Can you scratch the layer off with a sharp blade?
Place the note between paper (kitchen roll) and use a hot flat iron. Does the layer melt?
Can you wash the layer off using a cotton bud and


water 
methylated spirit
nail polish remover
