Paint em black and use as door stoppers btw i would go with the PAMP or the Perth Mint, because in my eyes physical is best. In this case, i don't think the price difference is big enough so go with whichever one takes your fancy; both are very liquid ( PAMP probably more liquid)
The Perth Mint Depository. It is government guaranteed and insured. https://www.perthmint.com/storage/help/faq-government-guarantee.html
Just to correct you here. Once you own physical gold or silver, there is no govt backed anything. Unlike money, where the govt backs the fiat currency on the promise that it's worth something to you or the person collecting the fiat. Gold has no counterparty risk, meaning it is money in its purest forum and the govt doesn't have to back it to say this is what's it's worth.
Yes it is, the gold in their possestion owned by you is government guaranteed, read the link I posted: https://www.perthmint.com/storage/help/faq-government-guarantee.html
