A YouTuber made a sword out of 100000 pennies

The price of Pennie’s may change by a little bit 

Well, it is believed that about 288 000 000 000 US pennies exist. By making a katana out of 100 000, the number of pennies drops by approximately 0.00003%. I don't think that would influence the price of a penny.

Probably .000003%-1% depending on what was melted 

Key date 1% chance was melt semi key date 40% chance was melted common date 95% chance was melted

If there are 288 billion Lincolns in circulation, then I think a better order of magnitude estimate is that there is less than a 0.000001% chance a key date is in the sword. 

Assumptions:

- key dates are only 1909-S, 1909-S VDB, 1914-D and 1931-S

- survival rates are well below 1% for these dates (I believe the actual figure is one or two orders of magnitude lower than this)

I'm actually more curious if they actually broke some laws 

“because I know you could destroy currency like, for jewellery” 

but melting it down into metal and turning it into a item is it considered defacing currency?

There's no US laws against defacing currency.  

Section 331 of Title 18 of the United States code provides criminal penalties for anyone who fraudulently alters, defaces, mutilates impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the Mints of the United States. This statute means that you may be violating the law if you change the appearance of the coin and fraudulently represent it to be other than the altered coin that it is. As a matter of policy, the Mint does not promote coloring, plating or altering U.S. coinage: however, there are no sanctions against such activity absent fraudulent intent.

U.S.C. 331 says, “Whoever fraudulently alters, defaces, mutilates, impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the mints of the United States or any foreign coins which are by law made current or are in actual use or circulation as money within the United States; or

Whoever fraudulently possesses, passes, utters, publishes, or sells, or attempts to pass, utter, publish, sell, or brings into the United States any such coin, knowing the same to be altered, defaced, mutilated, impaired, diminished, falsified, scaled, or lightened

if a example you're doing a science experiments with penny You can't "fraudulently" because we are not changing the value of the penny, we were doing a science experiment, not committing fraud?

P:S not American just want to understand a bit of American law

It’s ok to make copper and silver oz round from unreadable to g4 silver quarter, dimes, and half dollar. unreadable to g4 90% copper penny. only common dates

Only if the 90% copper penny is worth 10 cent or less by its condition. Silver coin is worth less then silver melt

When you take a 25 cent piece and try to pass it off as a Sacajawea Dollar, that's fraud. When you take a Buffalo Nickel, and scratch out one of its legs and try to sell it as a rare collectible, that's also fraud.

But when you melt a silver dollar and sell it for its silver value, or you use heat and pressure to turn a bunch of coins into a sword, that's genuine and legal.

Only Make silver and copper oz rounds with your logo mark only is fine.
