Donating granchildrens toys

I have 4 DGC,2 aged 23 and 21 living in San Diego California and 2 aged 7 and 3 in The Gold Coast Australia.
The 7 year old has been over to visit a few times with her mum, my DD, but not for a few years as my youngest granddaughter came along.
Anyway I had a lot of toys books games and craft things sitting in the loft.
I spoke to my DD whilst I visited her in Oz and I said to her they are just sitting in the loft doing nothing, so we agreed I should try to sell it all. But I then decided to look for a charity that takes toys ect for children who have nothing.
I have now sorted and Packed it up to give it to the Rotary Club, I know some people who are members.
I know some children will get some joy out of it, but I couldn't help feeling sad and cried a little.
I find it so difficult to be separated from my DGC
and it has happened to me twice, but I know I am not the only one.
would anyone else in this position, keep the memories in the loft, sell or donate to children who have nothing?
I know I have done the right thing, but feel still feel sad.
