Information from Cartridge/Packet collectors

I don't often ask for any help or advice from Milsurps however in this instance I would like to kindly ask those in the game on retail of these 2 Rem UMC packets.

As usual I only got a small amount of information from the seller (10+years ago) they implied that the DOM of these packets predated WWI.
If you look down the base of the front plate/s you will see that these were manufactured in Brimsdown in England by Remington not in the USA as is on packets I've seen online lately for Nitro-Club ones.

The condition of these two packets which are mylar wrapped is exceptional with no tears or dog ears though the colours are somewhat faded, well they are possibly 100+ years old.
Anyway I was just asking for a ball park figure as the USA made ones for the Nitro-Club on that site are posted at $249/USD.

I only included the Arrow pkt full packet shots as the Nitro-Club one is basically the same condition.
Thank you for your time and considerations.
