Why does a Krugerrand mintage figure on a COA from SA Mint not match the mintage on SA Mint's own website? [gelöst]

Why does the COA from SA Mint for a proof 1999 1oz Krugerrand say Max Coinage 1000, but SAMint's own website (http://www.samint.co.za/collectable-coins/product-mintages/) says the mintage is 2,787?
Numista (https://en.numista.com/catalogue/pieces6002.html) also has the 2,787 mintage.

Is there some subset of the proof coins that didn't come with COA in box + OGP?

Notice that your COA say "edition". It also notes that yours is one of 10 of that edition. Mints often play word games in their marketing strategies. The way those 1000 were packaged or sold for example but the total mintage remains the same for that particular coin. The remainder were sold differently. The U.S mint will take a coin from the total mintage and sell it as a "Product Number". They might add some to a set of 2 or more etc and refer to it as a different product number. One edition or product number may come in a display case while another edition or product number may simply come in a capsule etc. Regardless, the total mintage for that coin remains the same. That was 1999 and how the remainder were sold or marketed, I can't say.

Thanks.
