My mystery coin sender strikes again....

Once again, I received a mysterious package in the post.... This must be at least the 8th random coin set I've had from the "London Mint Office".

Everytime a new package arrives, the name on the front is similar to mine, but always has a twist to it!

NAME: MATHEW THOMAS

For example this time im Ms Matthew Tgomas. Previously I've been MATilda Tomasy and other variations of my name.

This has been going on for around 5 years or so, and it's been approx 6 months since the last coin arrived.

I do have a question - with every set that arrives, there is an invoice for £2.50 ($3) to cover p&p.
Q - Since I don't request these sets, am I liable to pay this? I've never contact the "LMO" about it and have never had any further requests.

The coin that arrived this time is actually 50% silver, rather than the clad crap that usually arrives with these sets.

It doesn't have much value to it as its a very common 1935, 3 pence. But still free silver is still free silver.

So to who ever it is that keeps sending me these. Thank you!!
