I just received this email from an eBay seller.
As there are only 3 known of these I am tempted to regard this as BS :ok:

The e-mail might be spam, but there are "plenty" of 1887 gold £5 coins around. The scarce ones (with only 3 known) are from Sydney mint. London mint made 54,000 for circulation and 797 proofs. Here's the NGC listing.
