How much is worth

I am trying to find the best way to get a proper value of stuff being put on ebay.
Is the best way simply to look at “finished auctions” or are there services. These are both electronics and thing I’ve had since childhood?

I don’t understand your question as being related to parenting issues on a divorce site. However, you can look up the value of most anything via the internet. Try punching in your childhood keepsakes, like, vintage bubblehead Barbie l963 and perhaps a ton of these babies will crop up. I hope you use the proceeds of your sales to buy some great things for your kids! Maybe you need to “surf” some other places…speaking of bubbleheads…
