keep the copper away from heat!!!!!!!!

?we use it at work and the steam pipes turn black within a month. look at the copper You buy from b and q still shiny. ?so my advice iis to keep in cool dry conditions

Define "heat" & "cool"

I would have thought it went without saying that few would store their coins adjacent to extreme sources of heat. On the other hand many would quite reasonably store them in dry conditions at room temperature between 18C & 22C, say.

The temperature that they are kept in does not gaurantee them their lustre. To ensure they are not affected by moisture, the temperature of the space they are kept in should idealy be about 4 degrees F above the surrounding space temperature. Moisure will not ingress into a higher temperature. If silica gel is placed with the coins, the crystals need regular monitoring. These crystals will saturate within a few hours in normal conditions. Silica gel comes in different forms. The older type silica gel is dark blue when perfectly dry and turns pink when saturated with moisture. The newer type is brown when dry and turns (blue I think)

The crystals therefore need to be visible and not in cloth bags. Idealy the coin collection and tray of crystals should be kept in multiple sealed clear plastic bags, with the crystals visible. If silica gel crystals are used, they are only beneficial if kept in their dry state. Saturated crystals will be more harmful than none at all. Silica gel crystals can be dried out in a microwave oven. Sealed plastic bags do not stop 100% moisture. Another thing that affects bronze lustre is sulpher. Tobacco smoke contains substances that quickly degrades lustrous bronze coins.

Hello Bernie!

Thanks for the info. I hate to say it, but it sounds as though hermetically sealed slabs might be about the best option then! I think TPGs do offer a slabbing service without the grading option though I've never looked into this any further.

Perhaps we could ask them not to bother with the identification of the variety either - just slab 'em up, please...

Just a thought.

I remember reading a while back that the TPGs won't guarantee that coins won't tone once inside the slab - so they obviously have done on occasions.
