How Much Silver Can I Legally Own in the USA?

By GovMint :

In the United States, there are no federal restrictions on the amount of silver you can legally own. You can buy, sell, and hold as much silver as you wish. However, transactions involving large amounts of cash, usually over $10,000, may require reporting to the IRS under the Bank Secrecy Act to prevent money laundering. Additionally, if you travel internationally with silver valued over $10,000, you must declare it to U.S. Customs and Border Protection.
