Jane Austen engraved £5 note thought to be worth as much as £20,000 spent in Blackwood cafe

A special £5 note engraved with a portrait of author Jane Austen has been spent in a cafe in Blackwood.

Renowned micro-artist Graham Short said he spent the money on a coffee from the cafe, as his mum is originally from town.

Graham has engraved tiny portraits of author Jane Austen on four of the new fivers - and each inscribed note could be worth as much as £20,000.

Graham Short works only at night and wears a stethoscope to engrave the portraits between heartbeats in order to maintain absolute stillness.

The tiny 6mm portraits of the novelist are accompanied by a quote and appear next to the image of the Big Ben on the new polymer notes.

The paintings are so minute that in some lights you can't see the Jane Austen portrait at all, while the quote is only visible under a magnifying glass.
