Wondering why a C64 VIC chip (fully functional) that I got off eBay had an 8565R2 label fitted on top of it: MOS 8565R2

I peeled it off to find this: MOS 8656R2

I haven't ever heard of a VIC-II (PAL) labelled MOS 8656R2. What is this - a mistake in the naming of a production run, or some variant other than the generally known versions?

(Note: The C64 Reloaded2 board that I tested it in does detect it as an 8565.)

    Updated to include picture of sticker as well. – Retrograde Aug 25 '19 at 21:40

    Now that's interesting. One guess: Typo when setting up the stamping :)) – Raffzahn Aug 25 '19 at 21:46

    Seems [courtesy of Google Translate :)] like a mis-labelled production run is also what the forum64 commenters find most likely. Interestingly, the date code and even the silver sticker itself is identical to mine. – Retrograde Aug 26 '19 at 7:51

    If this was an ebay purchase from China, quite a few chips are now getting shipped essentially repackaged/refreshed, with old engravings ground off and new pins fitted. The new engravings are sometimes an approximation of the originals. If you're really unlucky, the silicon inside is not even a close approximation of the original. – scruss Aug 26 '19 at 16:14

Other people have observed this chip in the wild, and it seems like the consensus is that these chips are from a mislabelled 8565 production run, where the stamping text has accidentally swapped the 5 and 6 digit occurances.
