Anyone Know The Value Of These ?

Welcome to the forum.

I assume you are thinking of selling on ebay or something like that. The short answer is that they are worth only what somebody will pay. The long answer involves research - look them up on ebay and see what people have paid in the recent past. Look at completed auctions rather than live ones. Some people offer coins like these for silly money, hoping for a bigger fool to come along and buy!

Would you pay face value + approx £2 postage + ebay seller's fee + seller's profit for any of these? I would only do so if I was desperate for a single coin to fill a hole in my collection.

My gut feeling is that they are worth a small amount above face value, but not a great deal. The tube £2 could be popular, especially if you can find the roundel £2 to go with it.

I regularly sort through bags of 50p and £2 coins from the banks and I just spend the Battle of Hastings, Victoria Cross and Mrs Tiggy-Winkle 50p's as I've found dozens, and the same with the Brunel, DNA and Act of Union £2's. The 1997 Guernsey 50p is also pretty common as it was the first year of issue and they made large numbers of them so they could replace the old-style larger 50p. I'd agree with Anaxmiander that the Tube £2 is a bit scarcer. The Magna Carta and new-style Britannia £2 are also less common than the others, especially if the Britannia one is dated 2015. You can look at completed sales on ebay to get an idea of what people will pay, but I'm afraid there's nothing really valuable there.
