I have 2 coin collections and have been offered money for them but to be honest not sure if I am getting ripped off. One is by John Pinches Limited and is called “Elizabeth our Queen” and is comprised of 25 Hallmarked silver ingots each weighing 26 ounces. It was a limited set of 5134 sets issued worldwide.
Now there was a mistake made on one of them and a replacement was sent shortly after purchase in 1981 but I kept the original I have the relevant certificate of authenticity.
The other set I have is called “Queens of the British Isles” and is comprised of 9 silver discs. It is a limited run of 5000 sets and was minted by the Birmingham Mint
Any info would be very welcome
