This is my first post so I apologise if it doesn't read well, or is not suitable for the thread but I thought I'd offer some of my own finds from checking loose change.
I have also found three separate oddities; with the 2012 Two Pence (die flaw), the 2012 Penny (die flaw), and the 2014 Penny (weak strike Obverse). All seem to be fairly uncommon (I have found two examples of the 2014 penny in 244 pennies, and 2 examples of the Two Pence error, although they appear different, the die flaw is in the same area of the coin).
2014 Weak Strike Obverse Penny
On the obverse, the strike for the Queen's head appears to be noticeably weak (see images below - comparison photo provided).
Normal Strike:
Weak Strike:
2012 Die Flaw Lion's Tail Two Pence
The 2012 Two Pence (die flaw) I have only found one other example online (eBay). Please see images below:

My Find:
2012 Die Flaw D.G Penny
There is a clear die flaw between the top of the Queen's head and the D in D.G.
