    You know, there's something you can take for that. ;)

    I'd be paranoid working with O2 and H2 .

    C'mon, who hasn't set up a simple H2 and O2 electrolysis with a battery and some water? We did it when I was 9, in 1964. We also travelled tens of thousands of miles in cars that didn't even have seatbelts. Oh, and we boiled ants in their own moisture with magnifying glasses and listened to Rat Pack records, too.

    Danger was our middle name.

    Not to mention the chemistry sets you guys had. How did any of you survive :mask:

    Our parents spent more time teaching us about "stupid" than is the norm today. Part of that was allowing us to learn things the hard way sometimes; today, that gets a parent brought up on negligence charges.

    Blind luck and a well-ventilated basement.

    That, and finding out about computers just in time to avoid majoring in chemistry in college. I was a bit clumsy, a bit absent-minded, and a bit ambitious; in a field where you don't get "Undo" or "Restore from backup", I doubt I would've survived grad school.

    Not even basement, outdoors on concrete. Seeing that hydrogen-rated regulators are found in the high temp soldering and welding supplies does open los ojos a bit, though.

    My current plan involves a vacuum plate, bell jar, vacuum pump, and hydrogen gas. Put the coins on the plate, pump the air out, allow the H2 in, and watch. No ignition source nearby.

    Solar heating, perhaps with Fresnel aiding, only.

    Yes, especially in busybody counties like Philadelphia and the contiguous - less so in places like Lancaster and Berks. Our Sheriffs outright promote gun ownership and concealed carry permits.

    Reminds me that one of the experiments Lavoisier did was to burn a diamond under a bell jar using a large lens to focus sun rays on it to prove a diamond was carbon. I have Fresnel lenses in each eye.

    Yeah, my eye lenses have serial numbers, too. Cataracts, or were they Rincolns?

    Cataracts, have them for several years now...when my eyes are turned just right in the light, I can see the concentric circles.

    Nice one Kurt! But your racially insensitive micro aggressions are requiring me to retreat to my safe space lol :hilarious:

    I never seemed to get the gunpowder to ignite from the Saltpeter , charcoal and sulfur . ;) Dang if I didn't try . Seems Illinois didn't allow the makers of the sets to put in the correct directions . Though we did make a makeshift "bazooka" from a CO2 cartridge stuffed with matchheads with a fuse , then put it in a long pipe aim and ignite .

    You needed potassium nitrate, not sodium nitrate. Of course, you needn't ask how I know. :D

    Didn't say you did, my response was directed to Insider.

    First of all throw out the total production numbers as they have nothing to do with anything. The total number of coins graded is what matters. Now I'm just going to use numbers from 10 years ago for examples here, and only from PCGS. But those braided red cents you mentioned, 10 years ago there were only 4,577 graded - 584 of those were Red. That's a whole lot bigger number than you're talking about. Indian heads - 9,159 graded MSBN, 16,548 graded MSRB, 12,596 graded MSRD. Still wanna talk about the proportion of Red copper ? OK, let's go to Lincolns, wheat reverse - 14,831 MSBN, 15,903 MSRB, 80,716 MSRD - more than twice as many Red, as Brown and Red Brown combined. And all on copper coins minted before 1959 - 57- 100 years ago. Throw in all of the memorials and you add another 63,000 plus. And that's just from PCGS alone. And those are all numbers that are 10 years old - think they've increased ?

    Now throw in all of those graded by ANACS and ICG, throw in all the Lincolns also graded by all 4 companies, then throw in all of the half cents and 2 cents graded by all 4 companies. Now add in the Proofs for all of them.

    First thing ya know you got a whole lot of Red coins. Way more than should have been able to survive by accident, or luck, given that we are talking about our most reactive coinage metal and that all coins tone - very quickly.

    You can get today's population figures straight from PCGS. Why are you using 10 year old figures?
    Lincolns - wheat;
    brown = 76,676
    r/b = 45,576
    red = 264,894

    HUH?

    Now let me ask you. If someone has a roll of 1944 Lincolns, how many people would bother to grade a single brown coin? Even if you go back to 1927 (just to pick a date), how many brown coins are worth grading? Even a brown 1909 (+- VDB) might be worth $20 in 63-RB. Who is going to grade that? And a 64-RB graded goes for +-$40. How many people would you advice to get that graded? Hence, mostly red coins are getting graded simply because the others are not worth grading.

    Ding, ding, ding - we have a winnah! This exposes the fallacy of getting hung up on pop reports - selective submission. People largely don't get garbage slabbed, except for strange reasons. You can't infer ANYTHING about a particular issue's overall pop from a PCGS pop report!!! I'll die before I buy the line that you can!

    People who obsess on PCGS pops are missing the VAST majority of what's out there! What's in PCGS plastic is representative of nothing particularly useful.
