Luna 24 Russian Spacecraft that landed on the moon

I'm not usually a big fan of artifact cards like Spaceflori displays, unless it's the kapton pieces by Terry Slezak and others who removed the foil from the spacecraft first hand. For some reason I love this card that was made up by Paul Hartunian, mainly because it's a lunar surface flown piece, regardless if it was an unmanned Russian vehicle. I have 5-6 of these cards and where can you find an authentic lunar surface artifact for $40-100 ? When I do presentations at schools, the kids love holding something that's been on the surface of the moon and I don't have to worry that they'll break something that's a rare artifact.
