I've three types of boards :
-regular (theyve been yellow on the backside ever since mid 90s but comics seem to do well , kept cold temp but no too col)
-Ultra Pro just bought (smooth on one side , when you buy acid free then thats what you expect to get.....should be illegal to call it acid free if it isnt or state say "only 60% effective - not for 3+ yrs storage")
-BCW (i think from them , this is un-coated/pure white , i assume its acid free ?)
I've spent 100$ so Im not gonna shell out any more , maybe to my BTAS collection otherwise its low value stuff (90s Batman , Tec , Robin , SotB , LOtDK)
Was no point buying toploaders either , unless i get pockets to have inside (worried about Cazale & Presley autographs)
To not use boards sounds like a recipe for disaster imo , acid or not
