“There Might Be Something Collectible In The Boxes”
Occasionally, your child may have something collectible in what you saved. However, significant value is rare. You may have bought dolls for your daughter that she didn’t play with and were kept in their boxes so they would stay in mint condition, but very few of them have high values now.
Suggestion: Toys make great playthings but don’t typically make great investments. If your grown child doesn’t want the toys, donate them to a thrift organization so another child can enjoy them.
