I would love to use coin trays, but can't afford a nice system yet. I also use the
PVC free
flips with an
attribution paper attached. However you do it, don't slab them. Firstly, ancients, as mentioned profusely above, are meant to be handled, so keep them free. Secondly, slabbing costs
money and unless you are slabbing high
quality expensive ancient coinage, you might end up paying more to truly and professionally slab the coin than it is worth (unless you slab them yourself with generic plastic snapping slabs like the little rounded ones). Thirdly, if you slab them and then wish to sell them, true collectors will dislike this and break the slabs to set the coins free (as they should have been to begin with). So, all-in-all, steer clear of this and enjoy holding
history in your
hands.
Best, Noah
