I'll be honest. You've already made up your mind what it is. No matter what anyone says they will be wrong. Take a Canadian cent and compare the size of the leaf to the damage on your coin. I think you'll find they aren't the same size, making your theory impossible. Listen to the knowledgeable people here, they know what they're talking about.
On the general topic of one design struck over another I have seen many over struck tokens. In all cases the previous design is easily visible in the areas of the new design that are blank. There are many blank areas in and around the design elements of a Lincoln Memorial Cent. Some token makers will flatten a previous design and then restrike as a die test. In those cases only portions of the original design near the rim will be visible. I think the coin as shown here is either a post mint damage or a struck through error. If it is PMD perhaps it was intended to be a counter stamp.
What a terrible person, he cheated you out of $0.01. However, if you still still believe you hit the lottery and all of the advise here was wrong, you can check the auction listings at Heritage or Stacks for the next few months to see if it shows up
Probably peruse Craigslist or eBay and it would show up. Though shouldn't sell for anything above face value. or check a local pawn shop and look for someone behind the cases with a big smile, as they probably had a good laugh a short time before.
I once found a Lincoln Memorial Cent in Canada. But it belonged to someone else. He took it to a dealer. I never saw him again either.
I am sorry that the OP lost her coin. I hope that she and any other new member will NEVER trust their coins to "some guy" they know. They offer to "look it up" for you and you never see them or your coins again. Even the crookedest dealer or pawn broker won't outright steal your property. They might give you a low ball offer but if they tell you they don't want your coins at any price you can rest easy that they are not worth keeping. Better luck next time.
