$10 bills have seen increases for several years, but only increasing in very small increments per year. With the possibility of inflation in due time, whether sparked by COVID-19 or whatever, it wouldn't surprise me if there may be a surge in the number of $10s in circulation someday, but there may still be more $5 bills in circulation than $10s by that point.
Of course, it could also be possible that the number of $10s in circulation might be creeping up because people may be hoarding them due to its scarcity, and the number of $10 bills being spent is drastically low, which explains why there were less than 20 million $10 bills printed upon the release of the Desmond series.
Also, I find it amazing that the number of $100 bills in circulation is increasing in leaps and bounds. With the $20 now in decline, at the rate the $20 and the $100 are going, I have a feeling there will end up being more $100 bills in circulation than $20 bills in five to ten years' time.
