Hit the water tonight and I think I found my 1st cob back is toasted measures 3/4 of an inch by just over a half inch. Do you think it is

You may have to do a bit more clean up and/or an acid test to tell.

Here's the back very worn and pitted

Put it in baking soda for a few days then we will see.

Was thinking of electrolysis bad idea?

How soupy do I make the baking soda

 

[cudamark]

I'd be more tempted to soak it in vinegar overnight and rub it with baking soda afterward, then rinse it good. Sure works good on silver jewelry and modern silver coins.

Thanks cudamark

I would post this in the Spanish Cobs Forum. Electrolysis is better for iron.
