Hello all. I was searching a coin roll today and I found this peculiar 1917 cent which struck me as an improper alloy mix. Now I know improper alloy mixes usually show in streaks But this one seems to be in the form of patches ? Not sure what separates this type of error from something "not an error"? I took some close up pics of the different intrinsic metal inclusions. Thanks for reading.
Looks to me as if it has met an acid. Take any wheatie and put a drop of even meager vinegar on it for only a few minutes, then compare the results.
not so much oddly cleaned, it was used in/as part of an acid battery (stack thin cardboard and copper pennies and stripped zinc pennies, soak in lemon juice or other mild acid wrap in ducttape you got a battery) open it up about a week later you will have a bunch just like that one. Hope that helps
Thanks guys for the confirmation and explanations.i definitely have a better idea at how this sort of thing could have happened. Least its still a pretty old penny. intriguing make shift battery design mr weasel. have you tried it? .
I have, low wattage but better with coppers and stripped zincs then the "current" method of just 1/2 stripping zinc pennies. I;m always working on some odd thing like this (presently working on a beta type stirling engine
we're talking 1-2 amps nothing really usable, will light a small led at best. Ended giving up on that project as even with a dozen of these in serial could not get the power I needed/wanted for a small motor. it would run but only for about 30seconds. Add to that the weight started to become prohibitive for the use I was putting them to.
Heh. I've seen videos of people on youtube showcasing their free power inventions. Wonder if you were one of them. Otherwise though I support what you do we need more innovation like that. Hope to hear more breakthroughs in the future from you!
This was my 1st stirling engine. The one I'm working on now will be a circulation fan for my woodstove It should/could cut my K1 furnace use considerably. my last attempt proved the woodstove gets to hot for solder seals so working with high temp epoxy this attempt.
Stirling engines run on temp differential. figure the bottom plate on the wood stove heats to about 400 while the water tank at the top keep the upper half at 212 max. The expanding and contracting air in the pressure tank powers the power piston. On a side note I work with 90% recycled materials rather then "new". for a few hundred dollars I could have all the parts for one precisely machined but what's the fun in that
make me a car engine that will run off steam. Maybe there is a simpler way to make one than the antique style . I own a big piece of property here in these beautiful hills of Kentucky and it is covered in large timber , so I have a endless supply of wood for energy.
