i have several copies of this par stamp in various old stamp albums in my possession. one is in an old Julius Lallier stamp album that i purhased severalo yrs ago . the album is from 1863. the stamp in this book is light green in color, lightly post marked,perforated on all sides and has been glued upsidedown into the book . all the stamps in the album (Lallier) have been glued as well and are from U S A and worldwide. i have several other postage albums that also have this particular 1 uncentesimo postage stamp in them as well . so i have multiple copies of this particular postage stamp. please advise of the possible value if u can. thank you kindly Mark L.
