Beethoven symphonies arr. Czerny & Liszt

[Essipova]

Can anyone tell me if my editions are RARE? Year?
I have Beethoven-Czerny Symphonies 6,2,5,7 individually arranged for one piano four hands by Czerny. BRANDUS editions, Prix 15 f. no copyright, oversize.

I also have Beethoven Symphony No 9 arranged for two pianos by Liszt (Mainz, Schott edition, no date).

Thank you.

I would be surprised if these editions were rare, but I'm not certain!

As far as I know, they are not "rare". Medium to well-done is a different question. Beethoven once expressed his opinion about arrangements of his works. Please refer to the relevant literature.
