Again those Canadian cents are trying to get my attention. I found another one yesterday oddly enough in the past month the four I found span four decades, 2006, 1997, 1985, and 1978. Still I will try to ignore them as much as possible.
Coin lots are generally full of junk coins meaning some are excellent but common while some are rare and damaged. For this coin from Greece someone insisted on turning it into a pendant.


Look at the coin above you see why overtime they become rare. Some person thought, "Whoa never seen this must be rare let me nail a hole through it and keep it safely around my neck." You can see marks where the coin was held down to drill/nail also it started to warp. This damage drops coin value to nothing unless rare. The question becomes is this one rare enough.
Book value places a fine piece at about $50.00 while auction values hover around $80.00. Nothing compared to the 1845(o) Drachma that in fine condition goes for $1,100. At this point dropping the value by 90% seems appropriate. It is still silver.
Here's the stats...
Type/Country: 1 Drachma / Greece
Year: 1833 A
Mintage: Not fully known, less than 1,125,000
Metal: Silver
Value: $5.00 in Damaged condition
So should you take that state quarter and turn it into a pendant? What if some future collector finds it and wants to kick you in the head?
Go for it. You can't play the "what if" game. I can only hope you do a little research in case you feel it might be rare but ultimately every damaged coin does raise the value for the rest that still float around.
Do you have a Greek coin and want to know its value? Leave a comment/question and I will do my best to find out the price and history for you.
