Hi Billy, and welcome to
Forvmthe
flips you are describing sound like the cardboard ones collectors use for modern coins ( top photo ) you should avoid these as they contains
PVC, which is harmfull to the coin over long periods. they also prevent you from handling the coin, and obstructs viewing and the space to write the required
attribution is severly limited ( plus in my opinion are ugly
)
the second Photo is what Crawforde was describing, these
flips will hold anything from the smallest coin to larger and thicker coins , the coin can be easily taken out, seen from both sides, lots of room for
attribution. Some of these also contain
PVC, so you'll have to be carefull where you get these from.
the ones from
Forvm are safe for long term storage, and as Crawforde said are thicker and of better
quality than most
here is the link to
forvm,s
flips or to the page they are on, they are called SUF500. Crystal clear archival safe coin
flips ( they don't show up in the seach for some reason )
