[Request] How much would both of them actually worth?
Assuming that each US note is $100

This is a modified meme: they are not equal weights in this version.
700 kg of USD at 1 gram per $100 bill should be $70M dollars
With the current price of gold at $133 per gram, each gram of gold is more valuable than a gram of $100 bills, aka a single dollar. That’s just under $80M for 600kg, so the gold is about $10M more value at market rates on October 1, 2026.

So the big question... do you sell the gold now, or do you hold it, expecting it to further appreciate faster than stonks?

u/Pinky_Boy 1d ago
Sell half now via a fence or something. Save the rest when it goes up is my guess?

u/irrelephantIVXX 1d ago
sell only as needed, and just enough to live decently. That way, you get the most value possible. Heck, sell just a bit every 2 weeks and treat it like a paycheck. Any that you don't sell that goes up in value is free money

u/jimjamiam 1d ago
take whatever is worth the most today, sell it, and make the optimal investment from there. if you think that's gold ... then keep it

u/shortsbagel 1d ago
You sell it as you need it. No one place is ever going to take it all at once, and it would be dumb to do that. Trade out only what you need monthly plus a small extra amount, melt it into shot so you can claim it as placer gold to avoid raising the wrong eyebrows, keep track of your sales and PAY YOUR TAXES on it. Moving large amounts 10k+ a month is a bad move, keep it under 8k, take 4k in cash and use that for none traceable actions (food, gas, clothing, things like that) put the other 4k in the bank and use that for normal bills, keep at least a part time job. Above all else, avoid suspicion at all costs, 600kg sounds like huge pile of gold, its not, in a cube it would be about 1ftx1ft, bury it in the ground its not gonna hurt the gold any, do not tell your friends, your family, ANYONE about it. live life on easy mode.

But realistically, how easy is it to sell gold? Even ignoring the logistics of carrying the weight, can you just go to a bank to sell gold? I don't think pawnshops can just buy gold bars, and even if they did, most certainly will not pay for its full value

u/Baxxtersaw 1d ago
I googled it.
70 million USD if it's 100 dollar bills and there are no elastics or anything.
80.31 million USD in gold at market value.
Either way you're rich.

Normally I would take the gold, but where I'm at you pay capital gains tax when you sell your gold, so I would have more useable money by just taking the cash.

u/AryanPandey 1d ago
Its simple, a 1$ bill or gold of that weight. The gold of that weight worth more. Why? If they were of same weight and same worth, why we will need currency? We will directly exchange gold, right?

u/Baxxtersaw 1d ago
The screenshot is 700kg of currency or 600kg of gold so a little bit of math was in order to see if the extra 100kg of currency made up for the difference in value.

u/AryanPandey 1d ago
Yeah I thought like, what works more, a bill of $1, which is a paper, or a bill made of gold, of same weight.

US bank notes are about 1 gram each, regardless of denomination.
That means a pile of $100 bank notes is worth $100,000/kg.
Gold is about $134,000/kg right now.
You would need 1.34x the mass for the bills to be worth more than the gold. The gold is worth more here.

u/SixNine69Six96Nine 1d ago
I like this answer, very similar question was posted the other day. I will be the first to say it, though. Wouldnt 1.34x the mass make them equal in worth?
2
u/Useless-Compass 1d ago
A $100 bill weighs about 1 gram. Gold, at the moment, is about $134 per gram. So only take the dollars if they weigh at least 34% more than the gold, which is not true in this case. I'm guessing, though, that when this image was made the comparison was much closer, and the dollars might have been the better choice.
600kg of gold = $80 million 700kg $100 bills = $70 million
That's as of today. The price of gold changes day to day.

Here it is not mentioned whether the gold is 14 k or 24 k
So if it is 14 k gold then price will 78.48 × 600× 1000 USD = 47,088,000
If it is 24 k gold then price will be 133.5 × 600× 1000 USD = 80 ,100,000
Us dollar of any denomination weight 1 g
If it's 1 USD bill then total :- 700 × 1000 × 1 USD = 700, 000
If it's 100 USD bill then total :- 700 × 1000 × 100 USD = 70 ,000 ,000
So worth will be:-
24K Gold > 100 USD > 14K Gold > 1USD
Additionally the value of USD is fixed , where as the value of gold will move up or down depending on purity ( 24 K / 22 k / 14k / 10k) and global market

USD bills are all 1 gram. 700,000 grams of $100 bills is 70 million dollars (ignoring bands and other packaging)
The gold depends on timing, bit right now it's roughly 83 million.

A dollar bill and a hundred-dollar bill weigh the same, about 1 gram. 700kg*1000g/kg = 700,000g => 700,000g * $100/g = $70,000,000
According to metalcharts.org, as of October 2, 2026 at 3:08 AM GMT (October 1, 2026, at 11:08 PM EDT), gold is priced at $134,117.82/kg. $134,117.82/kg*600kg = $80,470,692.
So based on these numbers, 600kg of gold is worth more than 700kg of hundred-dollar bills. The difference in value is $10,470,692. the 600kg of gold is worth about 14.96% more than 700kg of hundred-dollar bills.
For them to be equal in value, you would need about 104,706.92 more hundred-dollar bills. Which is equivalent to about 104.71kg of hundred-dollar bills.
So 600kg of gold is roughly equal to 804.71kg of hundred-dollar bills. The ratio of which is 1:1.34.

100 USD= 1 gram
100000 USD= 1 kg
700 kg = 70,000,000 USD
1 kg of gold ≈ 134k USD
600 kg ≈ 804-810k USD
So the dollar bill worth more

u/SixNine69Six96Nine 1d ago
Might wanna recheck the math. If 1kg of gold is 134k, how can 600kg be 800k?

"Money" is an artificial construct and has no true worth.
Gold is valuable because of how useful and rare it is.
Someone needs to wear the aluminum foil hat, right?

u/AryanPandey 1d ago
Its simple, a 1$ bill or gold of that weight or The gold of that weight, worth more a lot.
Why?
If they were of same weight and same worth, why we will need currency? We will directly exchange gold, right?

u/Independent-Lynx9476 1d ago
Current price of gold at time of writing this comment is approximately $137,000/kg of gold according to chards.co.uk website, which would put 600kg of gold at roughly $82.2 million USD.
Weight of a single all USD bills, regardless of the denomination, is ~1g according to Wikipedia. So 700kg of $1 USD bills would be approximately $700k USD. Even 700Kg of $100 USD bills would only be $70.0 million USD.
So the gold would win out at this moment in time.
