Question about 1994 Parkhurst tall boy/missing link autos

[chefjason]

So I am looking at these cards and I have seen 2 types, especially the missing link autos, all have the serial number /956, but then I have seen some without the numbering and some with, for example, the 2 missing link autos I have, have the actual numbering with both numbers and then some listed on eBay have no actual serial number but still have the /956 on the back, how come some cards have both numbers and others don't? Would It still be a certified auto without the serial number and just the /956? Or are those promo cards that got signed IP?

Some were issued in the HOF auto repacks that Dave & Adam's have been selling. I have seen a couple come out of those at MLS. These may have been leftover QC stock that was previously sold to D&A - potentially to have been used as replacements for damaged cards

But is there a difference between the ones with serial numbers and the ones without? Are they Ip autos as opposed to the ones it the serial number on the back

There was no difference, other than there was no serial number written on it. I believe they were just extras that were put aside to replace any damaged autos pulled out of packs
