I bought this Ronald Acuna listing on eBay last week, but I don't see it listed anywhere.  Is it the one that is SN250, as it doesn't say that on the card.  Any help is greatly appreciated!  (^:

Do you have the card in hand yet? It seems like the picture on Ebay of the back of the card is a scan of the base set but the front of the card with the auto is a scan of card # ACBU-RA from the autographs set checklist. https://www.cardboardconnection.com/2018-topps-chrome-update-series-baseball-cards 

My best guess at least. 

Looks like Topps pulled a Panini move. The checklist they published does not match what they sent out!

Your un-SNed card is actually here:

I'll see what I can do to get the right numbers on these!

I have the card in hand now.  It look like a regular Chrome card with the auto sticker on the front, and the regular HTM25 number on the back.

I saw several on ebay with the HMT numbering after seeing the original post here. The renumbering of the non-SN set is awaiting one more Level 8 member's approval. We'll see how well that works, and if it's good, I can get the parallel sets going. I'm really getting tired of card companies pulling this stunt. There's absolutely no excuse for this.

The card stock for this card is slightly more rigid and thicker than the base cards, if that helps.  How many do you figure were signed for this particular set?  250?

No way to tell for sure how many were printed.  Easiest thing to do is look at pack odds and figure from the ones that were serial numbered.  That will give you a pretty good estimate at least.  Of course, it is always possible that they release different amounts of different players of the non-serial numbered cards.  Acuna would be a likely selection to "short print"
