I agree, it is a cool-looking coin. I purchased one, just to throw into the overall collection. I'm really not that much into world coins, but ever once in a while, an oddity comes along that strikes my fancy. The Niobium metal, heated to a green oxidation, looks neat.
Yeah, Niobium is really cool, only it isn't usually colored using heat, rather it is anodized using electricity which produces the colors. Niobium is kinda unique in that it can be easily anodized using electricity and you can control the color by applying different voltages. I believe you can get yellow, red, purple, blue and green using low to high voltage. Here's how it is done link I've thought of trying to do it myself and make MrsSpud rainbow colored jewelery or something. I think the idea of using a paintbrush as the anode (or is it the cathode?) would be cool. Imagine painting rainbows on metal.
I bought an Austria 2004 25 Euro alpine railway coin graded ms68 by NGC a couple years back on ebay on a "buy it now " impulse buy. Paid $135 I had buyer's remorse directly after so I put it in my bin of shame to gather dust . I now see they are fetching twice that on ebay. link to current auction(not mine) Sometimes you just gotta trust your first impression
edited to add: I just double checked and it still remains the only NGC graded example. MY first and only population 1 of 1 coin!!!!

And what is that giant green spot? Last I heard, Niobium was not green.
Edit..."heat process and oxidation". Okay. Got it. I've done the heat damage thing before too.
it even has fluorescent and halogen bulbs on it
<< <i>I'm going to get one of the Latvia Coins of Time someday. Niobium/Silver with the Niobium anodized blue. I really like the design.
I love this heating/coloring process....never heard of Niobium until tonight.
I love the deep blue Latvian coin.
Surely the U.S. Mint can find a "profitable" use for this colorful metal/process!!!
Looks like an international thing for now!!!!!
Wonder if they can produce a jelly donut purple color for our resident Bear!!!

Here's a titanium/silver ti/au one I found while searching for more of those Austrian coins last night...
