Help pls !

So my friend's sister had passed away, hence why I was selling some purses on here a few days ago. However, I was not aware that they were counterfeit. She had fake authentication receipts (confirmed by a friend I went through after this ordeal on Poshmark). I thought they were real, and I didn't want them, so I figured I would do a price match and sell them on here. I am so sorry for any confusion I may have caused. I promise, this is the first and only time this will ever happen, and I didn't mean for it to happen in the first place. But I was trying to figure out how I could dispose of these purses instead of donating them and receiving a possible fine for it. I dont want to just throw them away because, to me, it feels wasteful. I do not have space for them, but I don't know how to safely get rid of these purses. If you could comment on here or message me, it would be so much help for me and my friend's family. Again, I'm sorry for any confusion or anger I caused.
