Double Headed Quarter Error Found 1932 Quarter

Thanks for posting if the coin is double sided and feels light its most likely a novelty or trick quarter that could be used in something like magic or even be used to run a scam of sorts. Just google double heads novelty coin or double heads magic trick coin. Weigh the coin, its from 1932 so its 90% silver. If the thing weight 6.25 grams then its the real deal and could be worth hundreds of dollars or more. If it weighs less its a Magicians coin or something along those lines. Also the quality of the coin does it look cheaply made? Do the ridges feel correct?

They are selling for $5.75 on ebay plus shipping likely. However they have a date of 1971 so I'm not sure. see image attached

Looks like they even have double sided tails, so if you were a magician and person called heads, you would through slight of hand toss the double sided tails coin. Good way to win 100% of the time lol
