What is the Allure of Leaded Chips?? (3 Viewers)

[upNdown]

hi

Ok, I found someone though a family member that has a Niton XRF scanner gun who has agreed to let me scan some chips. I don't have much for lead chips to have scanned. Does anyone have any interest in sending me some singles on popular sets to be tested? (scanner is in Iowa, so it may be a few months before I get back)

Yeah I’ll definitely have some to send.

I've noticed a notable difference between leaded TRKs and Paulsons. TRK did things right!

To me, what sets old school leaded chips apart from everything else is the feel and texture they acquire after being “broken in.” Excellent condition old school leaded chips that have soaked up years of nasty hand oils and hooker juice just have a feeling that can’t be replicated.

Welllllllllllllllllll…within an 8.22 - 11.39 range at least. I know there are a lot of factors here so just kidding around.

 

[softchewy]

Definitely different versions of some of those Kings Crown
The older set I have here appears to be heavily leaded

Aren’t TRK slightly smaller diameter as well?

ever so slightly, just a hair.

Nice, as long as it reads in ppm it’s good to go. Also test other areas of chip (same color) as they do have hot spots of lead, not by much but as you test different spots you’ll get the common range.

If you have all weight ranges 12g’s(some trks), 11.5,10.7,10.5/10.2(original leaded) 9.9/9.7,9.4,9.2,8.9/8.7(reduced/revised leaded and non(lower end)) and 8.2/7.9(non)

 

[PhillyB]

my understanding is the % is by weight (lead accounts for 40% of the chips weight)

Percentages is measured at PPM
1,000,000 PPM equals 100%
450,000PPM equals 45%
60,000PPM equals 6%

Etc, you get the idea.

Oh not me. I would only be submitting a very small handful of paulsons.

There is a world of difference between 40% by weight and 40% by volume.

Ok. I don't want to overwhelm this guy either. Right now I will start with these 8 chips and see how it goes. May throw in some NAGB chips just to see too.
Damaged Sterling Cruise $25
PCA $1
Empress $5
IOC Arc Yellow
IOC Fuchsia
IOC Sherbet
IOC Charcoal
I don't know what the black chip was before relabel

Fair enough.
Those ioc charcoals are heavy guys, I like them. Good chips to start with, Fushia is lightest so likely the least out of that IOC set.

yes, that was my point.
From my understanding, the 40%, 47%, etc quoted numbers were lead content by weight.
Darson was saying based off the by volume % numbers they posted that a 40% lead chip would be very heavy.
They appear to be thinking the 40% stat people are talking about was by volume when that 40% stat is by weight.

 

[Darson]

If it's % lead by weight then:

 

[softchewy]

Percentages is measured at PPM
1,000,000 PPM equals 100%
450,000PPM equals 45%
60,000PPM equals 6%

Etc, you get the idea.

Think you misunderstood.
I was trying to clarify Darson's confusion that the 40% (up to 60%) stats being stated as lead content are not ppms/volume... but % by weight.

 

[softchewy]

If it's % lead by weight then:

It is for the 40% to 60% numbers being quoted.
39mm Paulsons max out somewhere around 12g (heaviest one I own is just under 12g).

 

[allforcharity]

PPM for solid materials (and many others) are often interpreted on terms of weight/weight. Essentially, they are dimensionless units since the unit of measure for both numerator and denominator cancel each other out. The messiness of interpretation (w/w, v/v, or other) has excluded it from any real worldwide usefulness of the term in science and engineering.

The reason why lead content varies so much in chips made in the same time period is because there is a big variation in the "other" parts (inorganic and organic chemicals) that make up the colours, the fillers, the binding agents, the lubricants, etc.

 

[FDLmold]

There are some hot stamped Caesars ncv bricks that are over 13g each, but that is the Max I’ve ever seen for a 39mm Paulson.

 

[softchewy]

yep, bricks (these are just under 12g)

 

[ssanel54]

There are some hot stamped Caesars ncv bricks that are over 13g each, but that is the Max I’ve ever seen for a 39mm Paulson.

In my mind, I feel like those metallic gold hotstamp fracs were the heaviest chips I’ve ever handled. I’m blanking on what casino.

 

[AfterTheFact]

So I have found that these 1980’s made chips either weigh over 11 grams or under 10. Last pic shows they have the same amount of use.

If it's % lead by weight then:

And when they changed up the formula in 98 they added something to their clay makeup with the lowered lead amount, I think I heard it was zinc but I’m not sure as I didn’t test for that, something along those lines were added though.

maybe lighter ones are a later reorder?

I have a couple of near mint racks. Nothing under 11g.
Both racks weigh 1124g total each

What I was thinking too, that weight aligns with 2000’s average weight.

may be good examples to determine if you would be able feel any textural difference between the two (chip from each stack in very similar condition) if you couldn't lift them up and feel the weight

put them under a UV light to see how the arc yellow lights up

I have one but can’t currently find it…. I’ll keep looking.

That would nice to see, could also have a thread for chip weights from each casino and it’s denoms, it would be interesting and resourceful.

I did ask @Tommy if we can add that info in the chip data base. He was still thinking.
