Authentication for di faced tenners, by cest on Feb 22, 2020 21:53:35 GMT 1, Hi folks
I recently picked up a couple of di faced tenners with Laz letters as provenance...

I inspected them against my pest control certificate. On the COA, in the di left eye I can clearly see a brown dot, which matches one of my 10ers ...

For the other tenner I received I inspected carefully and it appears the pixelation paper and resolution is very similar to the COA.

With Banksy donating a tender to the British museum and these quickly rising in value and I am continuously seeing these come to market- how do the experts here authenticate these? Obviously without a COA or anyting from the bankster 2 guide folks, it is left to good old numismatics.

This is not a thread about whether anybody should care about these or authenticate them or that they are just junk ephemera... There are those of us who care so please leave those comments elsewhere.
