This may be long but I am soooo torn about what to do. The mother in me is fighting with the greedy cow in me.
i have 2 sons, both moved out years ago. They both literally abandoned everything they didnt want and buggered off to their new apartments leaving me to sort the mess. Im talking clothes, books, furniture, electronics etc. They are 26 and 28 now incase its relevant. My oldest boy did ask if I would hold onto his pokemon cards as he had nowhere to store them etc. Its the only thing I was asked to hold on to.As I was clearing the stuff they left, I came across the pokemon cards DS1 asked me to hold on to for him, also a folder that belonged to DS2, also full of pokemon cards. He was never into pokemon like the older one was and I reckon he hadnt even remembered he had it. They have sat in my basement for about 5 years now.
I have literally just discovered that some of the cards in Ds2 folder are worth money, like a lot of money. My Dd2 is looking through them and has only got 1/4 of the way through Ds2 folder and so far we are at $12000 
.
My dilemma is, do I tell him? I could do with 12 grand right now, but then so could he. If he knows about this he wouldnt even consider splitting the money, it would be all his. He abandoned them, I saved them, to be honest as I didnt know which book was Ds1 and was ready to throw them out.
The mum in me wants to make his day and tell him, the greedy cow in me says bugger him, they are mine now.
What would you do
These are cards from the early to late 90s btw, neither son is still into pokemon
