wait what, I know nothing about World coins, but are you for real? And also I love how the OP liked your post and thanked you for only the one saying that he's rich.. lol.
I remember reading an article about the coin recently. It was apparently given to a woman who had a cheese cart (like a street vendor cart). She had it evaluated and it was appraised for 7,000 but later sold for 3,500. After looking at her (the OPs) coin again, it has a pretty similar look. To bad about the hole, but if actually were real, it would be worth some pretty good cake or cheese if you will...
oh that's neat! To the OP, I would recommend it getting certified by PCGS or NGC if it checks out by the experts. Well worth the submission fees.
I would say a pawn shop or jewelry store should be able to determine what the top layer of the coin is made of. If it seems plausibly real, then submit it. I would be a bit surprised if someone put a hole in a valuable coin, but stranger things have certainly happened.
I wouldn't suggest a pawn shop. They don't know that much about coins most of the time, and probably not anything so "obscure" like this.
Most larger pawn shops have metal analyzer guns that could determine if the coin is plated or not. I wouldn't expect them to be able to authenticate the coin much beyond that.
If we're talking about that, I was once at a pawn shop where they were selling a proof ASE listed as Brilliant Uncirculated. I chuckled about how little that pawn shop must know.
How are you complimenting his coin if your (potentially) undervaluing it by many hundred's of dollars?
http://lunaticg.blogspot.com/2009/07/rare-silver-1-penny-coin-could-be-worth.html Well, at least we now know where the OP got the 2nd Picture from.
To set the record straight, I believe that there is a lot of "fluff" being bandied about as I do not think nor do I believe for 1 second that the OP has one of these penny's that someone drilled a hole through. I DO believe that it was plated and then holed and as such, is worth a cent. Besides, the OP's coin is a 1979 while the coin in the article, which has not been sold from what I've read, was 2003. The switch from "bronze" penny's to "copper plated steel" penny's (the supposed rare 2003 coin) occurred in 1992. As such, a silver or steel penny from 1979 is highly unlikely if not impossible. But I expect such useful information is of no use since the OP is not convinced that his coin is worth £3500.
