The 1952 E and 1953 A are listed as "rare", but their mintage figures are listed as 21,498,000 and 18,611,000 respectively. So how come someone considers these "rare" ??? Were they all melted down after minting before release into circulation? Or is this an error in the Numista catalogue?
Generally speaking, use of the words "rare" or "scarce" on eBay listings are meaningless, as are the asking prices. Only actual selling prices are meaningful
My search on eBay (German Democratic 10 1952E and 1953A) shows these results:
1952E - no items sold recently. Asking prices $7 - $20. Asking prices on MA-shops $12-20
1953A - no items sold recently. Asking prices $10-35. Asking pries on MA-shops $10
Yes, these date-mint combinations are an order of magnitude more valuable than others in the series.
