I'm certain that I read a passage from Tolkien somewhere expressing how disturbed/confused he was that anyone would want to make or possess a replica of the One Ring, being as it is a symbol of evil. But I cannot remember where I read this, and my Google-Fu comes up with nothing. Any ideas?
I am not certain that the passage in question was written by Tolkien himself; it could have been a commentator sharing their opinion as to how Tolkien would have reacted to such things. But it was in a published work, not an online comment.
