Sonic Sealing Slabs

Just can't see slabbing a coin. I spend a lot of time cutting them out of those slabs. I have no slabbed coins and see little reason for any. The only good thing about them is if and when selling one. If no intension of ever selling a coin, then slabs serv absolutely no purpose. So bulky and takes up so much room that could be used for storing bottles of Vodka or Gin.
As to sealing one, if not for a purpose of fooling someone as to who did it, simply use a Soldering iron. If hot enough, will simply melt the plastic together. Might look messy but should do the sealing. If good enough at using a Soldering Iron, could easily seal the entire slab.
OR get a large piece of Steel, place on a stove, turn on the burners and when red hot, run the ends of the slab accross that.
I just have no use for slabs at all. Even if I had a coin worth many thousands of dollars, into an Album it would go.

I would love to see some actual feedback from people who have purchased and used the table top spot welders with the slabs intended for the aforementioned.

That's a beautiful cabinet!

However, slabs should be stored in ziplock bags and then into Tupperware to prevent coins from changing. I fear that the chemicals that outgas from the wood will eventually seep into those slabs and affect them.
