I took a look at the Koha source code, and it seems that for some
barcode types, it is using this SQL to determine where to start
generating new barcodes:

  select max(abs(barcode)) from items;

It then increments the value that it obtains this way to use as the
new barcode.

So I suspect that you could fix your problem by creating a dummy item
that has the first barcode you want to use, minus one.

Note that I am not an expert and have not tried this myself.
