Difficult quiz - edges.

Coins have three sides. Which of these edges is on a genuine coin? This is difficult.

This is a tricky one. The edge is, usually, the absolute least studied part of a coin. Fantastic quiz, Insider.

I have some thoughts - but I'm going to let others post first so as to not potentially bias them.

 

I'll take a stab -

1. No - 4th from left looks funny
   
2. No - probably just a real gold coin with lots of wear, but I'm sticking with "No"
   
3. No - I'm 50/50, but they aren't uniform in size, so "No"
   
4. Yes - (probably maybe?)
   
5. No - better not be real

 

I'm thinking #4

 

4 also

 

#4 but given your comments I am going to say #3

 

4 but it's hard to tell without knowing the coin/denomination/country.

 

#4 looks like a Morgan with overlapping reeding.

 

Anyone know what caused #5? This should be the easiest one on the list.

 

Chinese ingenuity

 

I think 4 is the authentic coin. Looks like a normal Morgan rim to me.

It almost looks like one of those chocolate coins covered in gold foil.

 

Yes my first thought was if we are taking in the whole scope of the last 400+ years of world coins, I haven't much idea. Maybe Insider will narrow it down a bit for us.??

 

To paraphrase the words of Insider.... "objectively describe what you are seeing."

To expand: explain what you are seeing, and what that means. State the facts, form a hypothesis, and explain how the facts support your hypothesis.

Obviously he's not posting gold-foil covered coins. You recognize that something is off. What? Why? What could explain that? What's the key sign that you see that points to something being wrong?

 

I believe these are all intended to look like machine struck closed collar coins. Minting technology in the modern era is fairly uniform... there shouldn't be that much variation. If you're familiar with how US coins are made, most contemporary world coins aren't too widely different.

 

#4.

I can't count . . .

OK.

First. I think more than one of these can be genuine. Ya'll seem to be just guessing as if ONLY one of them can be.

Secondly. In @Insider 's NGC version of this post, he shows 6 edges, not just the 5 he shows here.

Thirdly I think #1 and #4 are genuine.

 

Oh come on. It was a joke. It looks like it’s plated to me.

 

All different ones

 

5 was cast

 

#2 with a damaged collar.
