I still have tons of LEGOS, but when my D taught for a year in NYC, the boys gave her permission to take a whole slew of them for her special ed resource room. Some of the kids she taught had never ever played with a LEGO before. When she decided to leave teaching after that year, she asked the boys if they wanted the LEGOS back and told them about a couple of her students who loved them. The boys told her to divide them up and give them to her students. We like to think that those kids or their younger siblings enjoyed the little bricks.
Sacred in my house and never to be sold:
Legos
Brio
American Girl dolls
LIttle Tykes Doll House
Marble Works
Multiple Fisher Price Play Sets (MULTIPLE!!)
Still have the Lincoln Logs but not so attached to them probably because the kids weren’t so into them.
My kids weren’t much into Legos. We did have quite a few sets-they’d build whatever it was and that was it. They had no desire to play with them otherwise. I do have a bin of them in the basement and just recently dismantled the A-frame house that had been sitting on a shelf in one of the kids’ rooms. Not sure why I continue to keep them. I gave away the Lincoln logs. My girls were never into Barbies. We had some but the only time they would play with them, and even then not so much, was when certain friends came over.
My absolute favorite thing as a kid were all the Fisher Price Little People sets. I had several of them-the barn, the town, the A-frame house. I would even use building blocks to make my own houses for them. I didn’t like the newer sets as much but bought a few for my kids. They didn’t like them nearly as much as I did!
We let go of the Legos, American Girl dolls, My Little Ponies, and Littlest Pet Shop.
We kept the Playmobil (2 giant bins), Brio trains and mech set, marble run from Discovery Toys, Polly Pocket (from when they were tiny) and a few other special things including Fisher Price little people from H’s day.
It will be nice to hand them off one day! If only…
There was a thread a while back about what toys you kept, and it made me realize we kept almost all of them. The most precious are the Build A Bears, Barbies, American Girls, Care Bears, My Little Pony, and dress up clothes. No actual Legos, but have a box of Duplos and K-nex.
I seriously need to get rid of a lot of toys, but so hard to do! I will take the middle ground on legos. My youngest has a number of built models on his dresser and will keep those. The buckets of random blocks can be reduced in size, with some given to charity. Will also keep the duplo train (got at a garage sale). Others will be kept for future grandkids of our own or other relatives.
Brio trains will be kept (although we have some imitation tracks that i will get rid of).
Playmobil and a few little people sets also to be kept, along with a doll house and people, the brand of which I can’t recall.
Books, I have kept the hard covers, especially those that were gifts but gotten rid of the many paperbacks (Berenstain Bears, Nate the great) etc.
Many of the stuffed animals are gone, but not the handmade ones or even the one Build-a-bear we have. I still have a couple of dolls from my own youth!
Didn’t mean to derail this thread and start including conversation beyond the original intent. 
Here’s the thread from earlier this year where people shared what they have kept:

While we may be packing up my daughter’s room, we do have the Legos, the American Girls, the Lincoln Logs, and building blocks and the miles and miles of Thomas Tank Engine tracks etc… safely packed away for the next generation.
We passed a lot of my kid’s old toys on to younger cousins, family friend’s young kids. They were all happy to have them. We also donated a lot of the toys to a domestic violence shelter…they always need toys for the kids living there.
I kept things like the booties that my grandmother knitted for D when she was born. The blankets my mom made for both kids, the Halloween costumes my mom made for D and S (princess dress and little red riding hood cape for D and Superman cape and pumpkin costume for S), the framed needle points with the kids birthdays on them that my mom made. The peter rabbit lamp my MIL gave us and the cute rattles she gave each of my kids…These things are heirlooms.
We gave S’s legos to a domestic violence shelter…they were so grateful! They really need toys…
My D sold her American Girls dolls on ebay…and she made a pretty good amount of money…since American Girls dolls are so expensive new, many people are perfectly happy to get a gently used one. She wasn’t interested in holding onto the dolls and I let her make that decision. I may have kept them, but we don’t have a ton of storage space…
My son’s closet is still filled with board games and Star Wars/ trek mementos. I’m sure he wouldn’t care if I gave away everything. Some years ago, I gave away all the little people places, brims and legos. The price of the brio board was so high, I bought the same size board at HD, and the paints, and made my own.
Sad, but I’ve worked with foster kids and the children of the food pickers. The one room schoolhouse for the latter was delighted to receive games, crayons, poster boards, well, you name it
Downsizing was an excuse to finally let go of so many childhood objects. Thankfully son was willing to trash some ugly school projects which cut down on the so far never touched bins. Timing matters. Wait until after college to dispose of their childhood things- when they are on to adult adventures. Then, a very few momentos. I still don’t understand why some HS math papers were kept, unlike creative writing projects. Oh, and do keep some things that mean more to you than the child at this moment in time.
It is better to let the current generation of children have use of so many toys and stuffed animals than to save them for a potential next generation. We can always buy new (all of us on CC have the money to do so) and if a toy isn’t available for the next generation they are unlikely to want it anyhow. Look forward, not backwards.
So- one of these years I will give away Legos- maybe.
For us, the Legos are staying, but for those looking for a new home for yours, I just saw this:

Legos, Matchbox/Hot Wheels cars, and Pokemon cards. They took the Pokemon cards with them…
