Silver bar from San Francisco Mint

cafrench

My father was an avid collector of gold and silver currency. This silver bar, with an overstrike in the serial number, was part of his collection, which he acquired the 1960s. I’ve seen previous posts that put the value of silver bars minted at the San Francisco mint from the 1950s at $150-$300 per ounce. Is this still accurate? Also, how does one tell if it’s authentic?

The 5oz bars tend to bring more than the 25oz class, but this is still a very desirable and historic bar.

To me it looks authentic just from the font of the stamps.

For value I would check auction houses for completed sales but your numbers sound right to me for a larger piece, where as the smaller San Fran assay bars can bring $1000 per Oz

Awesome inheritance, the error stamp is pretty neat.

In the 1960s few collectors cared about these and they often traded for little over their silver value, which was $1 something per ounce.

Today few collectors still care about these but they are much better connected by technology and limited demand for these is still far greater than the very limited supply, so today they are much more appreciated by those who seek them and that is reflected in the price.
