If these Orchid Series currency notes is in mint condition is protected by a plastic holder, you can either search on ebay, how much the dealers or even the sellers are asking. Numismatics will buy from you, if they are mint, if not, some will just buy from you plus a few dollars more, other than sentimental values; the currency notes is just the same value as it is printed on. Unless of course, the notes have some flaws, like watermark, printing errors, or some numbering series, then, even at that condition it command a premium. If you don't want the $1,000 , you can always give it to me, I don't mind to start a collection.
