i'm, ahem, no plastics expert, but this 1 i think i can actualy answer. bruce, who used to specialize in acg coins, got away from being associated w/ acg, & just decided to begin holdering his own coins. i don't believe these are from a "slabing company" per se, but rather just his preferred way of holdering coins.
that said, i believe he did rent alan hagar's slabing machine for this purpose.
Coins Card & Currency owned by Bruce Maag. As Dorkkarl says, he used to handle a lot of ACG material but now slabs his own through ACG's private label service. (Other known private label companies are S & G Rare Coins out of Florida, Rich Stiles, and NGS National Grading Service.)
