Homemade Coin Dies. Making a New Currency!

I feel like using a hydraulic press or a press of some kind would be a lot easier than trying to get a perfectly straight strike with the back of an axe, or even a hammer.

Nice job i have been learning how to cast with wax during the winter and in the spring I’ll be casting metal

I think you are better of carving the coin rather then smashing the coin

those quarters look so real you might get in trouble

Use a hydraulic press instead of the 🔨

I absolutely loved this video. It’s the first thing I’ve ever watched on coin making and I am extremely happy for it. Thank you.

This may be the coolest video I have watched today. I have been watching smelting videos for years and just now found you. Have you played with this more to perfect the technique?

What about using a vice to add constant pressure instead of sledgehammers?

That's meant to be whatever you want it to be it's called stock

👍

In 1000 years these coins will be dug up and be sold on ebay for millions

thx i enoyed this

You might try using a hydronic press rather than hammering

A press would make a huge difference

Hydraulic Press ?

Hi Lundgren Bronze Studios! Nice video! Interesting idea! I just subscribed to your channel! 😎

I wonder why you didn’t use one of the blanks to cast the coins.

I started counting all the ways that you were doing it wrong. (no offense intended) Your whole premise shows your misunderstanding of metal. The stump idea was slightly better than using a bed mattress. Your etching was backward and your axe hammer was slightly better than stamping with your foot (coin stamps usually use 2-5 tons of force). Your mold was an incredibly shallow and not usable in any way. THEN to make things worse... you use a hard metal such as brass (nordic gold).

Can you pl send me your email address, I need to do some business with you.

Very interesting video!
I have some suggestions to you:
•You could try acid etching for more details. It would be much easier than making it by hand.
•On the hammering process, you could make a system where a weight drops on top of the coin stamp. It is much easier than hammering it one by one

Heads = Obverse
Tails =Reverse

You can remove small amount from punch edges to ease removal after punching
Great job though👍

Interesting art sir, good job. How about some hydraulic coercion?

Use silver

year gonna be mirrored

If you had a lathe maybe you would make coin blanks by casting a round bar, turning it to size, maybe knurl an edge pattern, then part the blank off. Still, stamping from flat sheet might make more sense economically. But isn't it more fun to do it your own way?

Well, done. very well done. I'm probably going to pour aluminum or copper into plaster. I will make wax blanks and burn out the wax in the drying process. But dude, well done.

To strike accurately it takes two people. One holds a rod or blank of soft steel (a sledge hammer seems convenient but striking hardened steel on hardened steel can be dangerous) the die and the other strikes the intermediate piece which transfers to the die without slipping.

Would have been much more efficient and consistent to press them with a hydraulic press even a bottle jack would have worked you can get a 2-ton pneumatic bottle jack from harbor freight for like 30 bucks. I also think you're blanks could have been made more efficiently and consistently by casting a solid rod and then cutting them to the required thickness with a bandsaw. Bronze is quite soft so it would have been barely any wear on your blade if you had a half-decent blade🤷. Still neat though. Good job.

Great effort....love the video......if you were able to create this in your first attempt, you will become awesome at engraving.

use a carjack as a press

If you use a hydraulic press, that will be more even and consistent for the stamping. Attach the dies to the press. I suspect splitting the holder into (at least) 3 (and then allowing them to be secured in place-like a vice-would allow the coins to not get stuck after pressing. The holder might need some interlocking nubs to withstand the outward pressure.
Modern home CNC (etc) machines might help get a more finished die (when the kinks are worked out of the process).
Depending on the metal, you might also just engrave some coins out of sheets of metal. Not necessarily as polished though.

And, for the record, I have zero experience with any of this, so this is very much an "outsider" perspective. I only give ideas as requested.

Can you make 1trillion dollar platinum coin please?

Should have just bought some brass round stock and cut your discs to fit, and buy or make a hydrolic press. Also that steel isn't going to hold up very long you need thicker strike plates like an inch or two at least. Also I know most people that talk shit in your comments have no clue what they're talking about so ill add that I have a bachelors degree in advanced metalsmithing from Southern Illinois University. Overall not bad.

After heating the blanks up in the furnace, you might try using a press with a bottle jack set up to compress the dies

Maybe pour a rod, cut discs and press using a bottle jack set up

I should think that using a hydraulic press like a car jack would work better.
Also, at least until you get the procedure down right, you might want to try an even softer metal like aluminium or copper.

Brass, you used brass

Maybe use an Arbor press instead of hammering?

If the government is printing money then why can’t we do the same?

When I was a kid, I hand drew a dollar bill with crayons on a paper and it looks so real that fooled the ice cream man and I lot like bunch of ice creams, candy and toys during the after school program.

Then when I was in my teens, I started printing dollar bills for front and back side and damn it looks real!

I'm just thinking hydraulic press.

It might take more setup to do, but you could harden the stamps, then soften the metal to be stamped, and use a very heavy press to crush down onto the blanks. A couple ton hydraulic press could do the trick.

Super cool idea and work. I'm make ancient replicas in real 90-97% silver and I'm interested in some business with you if you can supply die's. It would be interesting talking to you. Kind regards, from Copenhagen DENMARK (EU). I see you have a Swedish family name :) Lundgren

Well done! I love those coins!
BTW you don't need to heat up the blanks so much. They are at their softest point after pouring them. Since you had to sand them, you basically work hardened them. So, it was a good idea to heat them up again to anneal (soften) them before stamping, but they don't need to be hot like that while you stamp. The metal stays soft, even after they cool down, until you do something to work harden them again. Nonferrous metals react to heat & cold differently than steel.
I really enjoyed this video. You definitely got my sub.
