No, peanuts were phased out as currency in the late '70s (Jimmy Carter scotched it...). A small practice amp for electric guitar..? So many options, from the Vox Amplug and similar (plugs into the guitar to feed headphones, so no speaker, from £13 upwards, Thomann...) up to any 5w amp with battery power (£15, Thomann...), or Fender Mini-Twin (£42, Thomann...). There an enormous range of small amps with headphone sockets. Have a look through the Thomann range, or visit your local music shop, maybe..?
