Hi all – I'm suddenly fascinated by lathes, coining presses, and other machine tools. I feel like I completely missed out on a major technological...
Hi all – The center disc of €1 and €2 coins is composed of three layers. But the specs are confusing since they just say Ni7 and Ni12 for the core...
My two cents: Be sure to buy on the dips. Always. Margins are too tight to be buying on arbitrary days and prices. You can define your own dips...
No chopping necessary. It's based on the assumption that the official diameter of the coin is the max diameter, since a reeded edge gives a...
That's fascinating, thanks. It's interesting that the design features, like the text (letter E in this case), are almost as high as the rim. This...
Yeah, that thickness claim must be wrong. (Unless the strike knocks the rim down some from what it was coming out of the upsetting mill, while...
Yeah, I forgot to reply to that bit. It has nothing to do with anything I'm talking about. I was saying how surprised I was that US coins like the...
Yeah, I was puzzled by the Mint's claim about the "same thickness" too. It would be nice to have a simple table of all dimensions at each step in...
No, I was just noting that the coin has less volume than a perfect cylinder of its diameter and thickness/height. A coin isn't a perfect cylinder....
Yeah, I think you can probably use Canadian quarters a lot of the time as well. That's always been true, since the dimensions are a near match....
No money in forging pennies, at least not from the correct metals. The melt value of a modern zinc penny is one cent now, while dimes take 2.8...
Hi all – I always check the Coinstar machine when I go to the supermarket, since the cost/benefit function is similar to wearing seatbelts in...
Right, agreed, never said there's a change in volume. Note however that the mint says the strip or planchettes arrive the same thickness as the...
I'm referring to the design features being higher than the field, not claiming that striking adds volume, which is impossible for solid metal at...
Hi all – I'm surprised by the amount of "missing" volume / weight in circulation coins compared to a smooth cylinder/coin made of the same density...
They force crypto exchanges like Coinbase to report your activity. This is why Coinbase, Kraken, et al require all sorts of information from you,...
Hi all – I've been reading about industrial "parts washers" that use hot water and detergent or degreaser to clean small metal parts. They seem...
You keep making evasive statements that aren't logically relevant. I said they don't report mintages anymore. You said you have records going back...
