echizento => yah, it's actually not too dangerous for me anymore, for I am now basically merely an office manager (not nearly as glamourous as it once was for "young" stevex6) ...

=> now I merely send my young engineers into the mine with their spilly viles of nitro!! (obviously I'm just joking) ... it is actually fairly safe nowadays => the mine is totally cleared before any production blasting occurs

For someone like me that hasn't seen an operation like this it would be a thrill to see from a distance.

They probably just had a large supply of nickel in the area. Neat coins I like the animal reverse.

Nowadays, it's easy to miss the significance of these cupronickel coins, until you consider that very little if any, nickel objects were made during this period--and none in Baktria. These coins have boggled archaeologists for over a century; earning the namesake "Baktrian Nickel Theory" to explain their existence, which once attributed the source to China. China did produce a cupro-nickel alloy called "paitung", but the earliest relics date from the 3rd Century AD. Meteoric iron-nickel was once fashioned into blades and other implements, but cupronickel requires more refining. Where and how this nickel was mined and why it was fashioned into these coins of Baktria remains an unanswered mystery, possibly lost to the sands of time.

They probably abandoned the minting of these because of the hardness factor of nickel. It's equally as hard as iron (Mohs 4) and probably made the dies wear quickly. Tin (Mohs 1.5) would be a much more friendly element to use with copper (Mohs 3).

And nickel melts at 2647F, versus 1983F for copper. With tin melting at just 450F, bronze is considerably easier to alloy than cupronickel--it's probably why there was a "Bronze Age" but not a "Nickel Age".

I always liked the meteoric source theory but that is because I am an old romantic and not a scientist. It would seem these would have one or both more iron content or a type alluding to the meteor if the material were picked up from a fall. The whole matter of why the metal was so different and the types so ordinary bothers me considerably. If the coins weere from a meteor, I would expect the nickel would be valued above gold and the coin workmanship more special than silver. It is not. That takes us back to a giant 'don't know'!

Meteorites in ancient times were revered as 'gifts from the gods'--I'm doubtful they would be made into cheap, expendable items like coins, unless they were unaware of the metal's source? Meteorite iron is resistant to corrosion due to the nickel and was a valued material for blades. Copper is not very common in meteorites, but perhaps a meteoric source of nickel was alloyed with copper? From what I've read, these coins also contain iron and cobalt, which is present with nickel in meteorites, but is commonly found with terrestrial sources too. Whatever the reason, it's really an interesting mystery!

I'm sure you've all seen this article (pg 60,61) from the fifties. But just for the record.........http://adsabs.harvard.edu/full/1953Metic...1...60B

Maybe we could start a new 'time travel' theory since the percentage of nickel and copper is nearly what modern coins use. Somebody went back and tried to get em going on this method.

Seriously though, they are really cool coins and I would like to have one, especially the one of the Panther types. They are up there though.

Meteorites come in a wide variety of sizes and compositions but I have never heard of one with significant copper. The common iron nickel ones would seem to be much better used making knives. Stones valued as a gift from the gods tend to be larger but many falls take the form of a million small pieces (my favorite is Sikhote Alin from 1947 that peppered Siberia with nice little collectibles). Few were worship size but there were enough we each can have some:

I seriously doubt the meteorite theory but it is one source of surface nickel on Earth so I suppose it is possible. Could a fall before 200 BC have been so completely scavenged that we have no evidence of it ever having fallen? Good question.

#19 Aigina AR stater early 5th century BC
My-Top-25-Coins-Maybe
We need to start this lesson with a bit of turtle anatomy. In life, turtles have one head, four legs and one tail. On coins of the island city state Aigina, turtles should have the same parts but the fact remains that many are weak or missing some of the parts. Price to collectors depends on which parts are clear. It should come as little surprise that most collectors would prefer a coin with the head. My coin has the head and even shows it clearly enough that you can see how it is turned to the side with open beak and one eye still indicated. That is why I show my photo swimming left rather than, as often seen, with the head up. My coin has one leg complete enough that it clearly shows the three claws. The other front leg has no foot. Rear legs? Tail? Nope! My coin made the #19 position in my heart partly because of those claws. You don't see them everyday. More, however, I like the fact that my coin was struck on a silver nugget rather than a carefully prepared round flan. One would expect coins of this nature to be earlier but the style of the reverse punch and turtle details suggests the coin is not terribly early in the series. I am not well schooled on the details that allow precise dating. At 12g it is a nice big chunk of silver and early in comparison to other large coins in my collection. Sure I'd like one with four legs and a tail but this one is a favorite with me since 1999 and easily deserves my position #19.

Did I mention these coins are both thick and high relief? They are hard to store in standard holders and can be thicker than some trays. Pleas don't force one into a slab!

Ancient copper nickel coins! I had no idea! Very very cool!

The turtle coin is awesome! Very nice eye appeal!

Beautiful thick coin, I like that it was struck on a silver nugget. The turtle looks like he is smiling.
