Following the hint by Xmas and unsure whether there is one or more Ricardo(s) active on the forum (Ricardo Miranda : "he only needs to post the six digit code on the cassettes")
I found the following links useful to (I hope) identify the "real" APX-100.
https://en.wikipedia.org/wiki/DX_number explains the structure of DX numbers
https://www.flickr.com/groups/67377471@N00/discuss/72157634429783414/ this discussion thread contains a number of DX codes, among them:
000234 AgfaPhoto APX 100
017711 AfgaPhoto APX 100 (New)
http://www.yumpu.com/it/document/vi...lm-international-imaging-industry-association gives free access to the 2008 version of the I3A document listing all DX codes. For instance, for APX-100 : 1-7, which is coded into 16*1+7=23, consistent with the 0023 middle digits listed above for AgfaPhoto APX 100 (read the Wikipedia document). So much for the Internet rumors (trying to stay polite) that anything with expiry pas 2010 is "New", or anything "Made in EU" is also "New".
A correction to my previous post. The 12/2011 films are "Made in EU", while, the 12/2014 are "Made in Germany". All have the 0023 middle digits in the DX codes, corresponding to the 1-7 allocated to Agfa by I3A. All say "produced for and distributed by Lupus Imaging". I believe both kinds are from real Agfa master rolls.
Just to bring this thread to a conclusive end: could somone
(a) confirm code x1771x for APX-100 with "New" on the package; interesting to know that if one breaks down the 1771 (again see Wikipedia article) as 110*16+17, the 110 part is a production code assigned to Harman Technologies by I3A; see controversy in

(b) provide the DX-code for a sample of Rollei Retro-100, rumored to be real Agfa APX-100.
