I'm a bit ashamed to upload a pic of these here as they were not stored in airtight containers since purchase; had no idea they would devalue if not but hey ho...
 
Can someone give me an idea of what the floor is on these? Obv. they are funded and intact (i.e. hologram sticker untampered) but .. as I said.. there has been some oxidation over time.

I am considering taking them to a coin collector in order to have them cleaned - an anathema in the world of numismatics I know - but people like shiny stuff....

One is silver and other other silver with bronze (?) highlights.

Will upload pics in a day or two if there as interest. Would prefer to sell both together but would be ok to sell one at a time.

Am London (UK) based. Also I have no idea how escrow would work if I do sell these so please give me some pointers in public replies.
