We know Goblins consider any object made by them as belonging to them:
“You don’t understand, Harry, nobody could understand unless they have lived with goblins. To a goblin, the rightful and true master of any object is the maker, not the purchaser. All goblin-made objects are, in goblin eyes, rightfully theirs.”
“But if it was bought —”
“— then they would consider it rented by the one who had paid the money. They have, however, great difficulty with the idea of goblin-made objects passing from wizard to wizard. You saw Griphook’s face when the tiara passed under his eyes. He disapproves. I believe he thinks, as do the fiercest of his kind, that it ought to have been returned to the goblins once the original purchaser died. They consider our habit of keeping goblin-made objects, passing them from wizard to wizard without further payment, little more than theft.”

And we know that all Galleons are made by Goblins:
"You see the numerals around the edge of the coins?" Hermione said, holding one up for examination at the end of their fourth meeting. The coin gleamed fat and yellow in the light from the torches. "On real Galleons that’s just a serial number referring to the goblin who cast the coin.

So do goblins believe all wizarding money ever made belongs to them?
