More than 50 new additions have been made to the Ongoing Checklist. I will continue to add more as time permits. I know that more that have shown up over the last few years but since so many are very minor, I will wait until something substantial turns up.
If you have any additions that you feel should be added, please post them in the comments section here or in the original 1990 Pro Set Errors & Variations Master Set Checklist blog.
The following items will not be added to the Master Checklist:
-The printer’s scrap cards that have flooded eBay the last few months. This includes the blacked-out cards, smeared, miscut fronts/wrongbacks, errant color tone, smudged, etc. These cards are printer’s waste and were NOT pack-issued or meant for distribution. They were cut from sheets pulled from garbage bins. While really fun to look at and collect, they should not be considered essential to a master set.
–Wrong front/back cards. Again, these are really cool but are seldom found pack-issued and were usually cut from sheets found in the trash, making their way into the market illegally.
–Miscuts.
–Draft Day blank back/front proofs. Great, recent discovery variant proofs for Jeff George and Keith McCants draft day subset but not pack-issued or legally distributed.

The George/McCants draft day gold border cards were actually supposedly distributed at the draft that year and are a well known legitimate issue.
I have yet to see a complete issue. Only blank front/backs. Also, I believe they didn’t show up on the secondary market until a few years ago. As an avid pro set collector since 1990, I had only heard of the regular issue draft day cards being distributed. If anyone has a copy of the fully printed gold bordered issue, I love to see a scan as well as any info substantiating their distribution at/on draft day.

I have a 1990 pro set Super Bowl Supermen Card with jim taylor on the front and willie Lanier on the back.
I was going to delete this bookmark and was taking a last peek. Glad to see you are updating your site after a 1 year hiatus. Always good stuff and I’ll keep you in the Favorites list.
Hi Dave,
I have been adding info to existing blogs/lists here and there over the last year but yeah, this is my first blog in that time. I have very little time to commit to this anymore unfortunately. I’ll add info as often as possible.
Thanks.

Hello,When I was younger I bought boxs/cases of these cards.After finding your list couple weeks ago I am nearing the end of quite a few monster box searches.Any idea of what a complete master set of errors would sell/appraise for?Im sure supply/demand,the price of rice in china and the lunar eclipse would all come into play here :} Just wondering/pondering ebaying everything or getting the 20-30 cards to finish the master set.After 20 years of collecting cards/coins etc…Think I would rather a collecter have these instead of breaking them, paying ridiculas ebay/paypal fees on top of that and ending up with same amount of money.I may have 150-200 errors,alot of the 2-3 astrick cards.Sadley,the time has come to sell alot of my stuff.
As another data point, I grew up in Indianapolis, where the Jeff George draft cards were hot sellers. I picked up a copy of the gold bordered cards in the 1990/91 timeframe. As the others that have appeared, these were 8 different cards: 4 with fronts and blank back, 4 with backs and blank fronts. While I cannot confirm that the cards exist without blank backs, I can confirm they were in the market in the very early 90s.
Just for a point concerning miscuts or faulty registration as not being included on the master listing. I purchased a case & 1/2 of series 1 22 years ago. I took these faulty miscuts & misregistered cards out & put them in the screw down holders. Have not been in the light of day for many years. These all came out of those packs. I guess there is no way of proving my point. To me I know they are legit. I think I have a legit & special card for the master list. Every pack had a 10 cent redemption card on of NHL licensed merchandise. I pulled a blank back card for the 10 cent redemption. Could this be considered for the list? Please give me your feedback.
Neat find! It should have some value to a Pro Set master set collector. I know that I have sorted through 3200 count boxes of those discount cards looking for oddities and have yet to see anything like that. Good luck!
Thanks for the interest & yes it is available to right collector. Have a great new year. Jackson
I have an error card that i am trying to find any info i can on. You may be able to help. it is a 1990 ProSet Joe Montana MVP Super Bowl XVI card that has no back–“No Back” card. I actually have a display plate that has the card printed correctly and beside it has the error card. Where can I send a pic for you to look at? Any idea what it could be worth? Thanks
I just went through the Series II box I bought as a kid, and I found a couple of errors I don’t see in the list. #751 Ken Clark has a blue ink smear that goes all the way across the front from near the top of the white strip with the logo and “PRO SET PROSPECT” down to the tops of his shoulder pads. I have 2 cards with the exact same smear. They were in packs, so it seems to me they should be included.
I also found a #437a Shane Conlan, I have another #437 which has the B corrected, but there is a thin, broken black line on the back going from the edge of the picture just below “TOTALS” up and right and ending between “Buffalo” and “50.” Looks like a hair got onto the plate.
Hi. I loved what you said in the article especially about leaving the printers scraps
and wrong backs out, but I have to say that when I originally began collecting this set I pulled quite a few varieties One in particular is a wrong back but it also has only half of the printing on the back.. And I DID pull it from a pack. And recently I discovered an error I have not seen mentioned. I would like to send you pictures but don’t know how to do it. If you would like to see them please send me your email address and I will send them to you promptly. Thanks
I know that wrong back errors can come from packs, but since so many (the grand majority) come from printer scrap sheets stolen from the facilities, I don’t bother listing them.
I just went through a box of about four thousand 1990 Pro Set football cards and found the usual errors but came across an Andre Ware RC with his fingers having red and white stripes like a candy cane. Wish I could post the pic here but that doesn’t seem possible.
