I have what appears to be some vintage .470 NE ammo sealed in leaded tropical tins.

One tin is totally unmarked except that ".470", "Solid" and "500 G" are hand-written on it in old-fashioned script.

The other tin has the tattered remains of a Kynoch label on it. What's left of the label says the ammo inside is .470 Express, 3 1/4 inch, but nothing else is legible.

I'm like a kid on Christmas and want to open the tins.

Should I?

I'm quite sure that I would open one.

The tins themselves with none or at best mostly illedgible original labelling, are really of no value in that state. The ammo in the tins could be usable or collectable in their own right sans the tins. Open both and use or sell the ammo.
