COPP
Sprott Copper Miners ETF
stock NASDAQ ETF

It depends on what you want. I personally own physical silver (as well as some gold). I went to a local gold and silver location to purchase my silver and I ordered my gold for one of the major banks (I live in Canada).
If you don't want to go down that route, you can purchase different funds that give you direct exposure to silver and/or copper.
Here are some options:
Sprott Copper Producers ETF (COPP). This gives broader exposure than one miner and reduces single-company risk.
Global X Copper Miners ETF (COPX). Broad exposure to global copper mining companies.
abrdn Physical Silver Shares ETF (SIVR). Another bullion-backed way to track silver prices.
iShares MSCI Global Silver and Metals Miners ETF (SLVP). Diversified exposure to silver-producing companies

If you are buying physical metals, you may want to shop around as there can be differences in what each company will charge on the spot price(some banks in my area will charge more. I'm guessing its some sort of processing fee?)
