https://thepiperscove.com/ has some original Mackie diced bals in stock. They recently found them in a storage bin, new in the original package, thought to be over 20 years old. I don't think their website accurately reflects what they have in stock so I would email them directly with what you are looking for (color, dice, size, etc.) and they will check their inventory. Price is $99, same as the new ones from scotlandshop.com, but if you're in US/CA you might save some money on postage and customs fees.
