Because of reasons, I’ve had cause to dig out my old POG collection and take detailed measurements of them. Here’s what I’ve come up with:
A POG Milkcap measures:
- 41.37 mm or 1.6285 inches in diameter.
- 1.25 mm or 0.0490 inches in thickness.
- Forty POGs weigh 1.65 oz or ~0.041 oz per POG.
- Forty POG measure 2.0310 inches in thickness
An off-brand Slammer is:
- 42.80 mm or 1.6850 inches in diameter.
- 5.91 mm or 0.235 inches in thickness.
- 0.30 oz.
So, a Slammer is approximately 4-5 POGs in thickness, about 1.5mm larger in diameter, and weighs approximately 7-8 times as much as an individual POG.
