The Two Pound coin you refer to is a 2005 coin commemorating the 400th Anniversary of the Gunpowder Plot by Mr Guy Fawkes and his friends. The edge of the coin has the inscription "REMEMBER THE FIFTH OF NOVEMBER".
What appears to be a backward "7", is actually a stylised "5" if you look very closely.

To find out how much £100 in two-pound coins weighs, we can break it down: **Value of coins**: £100 in two-pound coins means you have 50 two-pound coins (because 100 ÷ 2 = 50). **Weight of a two-pound coin**: A two-pound coin weighs about 12 grams. Now, multiply the number of coins by the weight of each coin: [ 50 \text{ coins} \times 12 \text{ grams/coin} = 600 \text{ grams} ] So, £100 in two-pound coins weighs approximately 600 grams, or about 1.32 pounds.

The Pound or Sovereign was not introduced into the British system of currency until 1817 when it replaced the Guinea, and the first Two Pound coin (Double Sovereigns) was minted in 1820.
The One Pound coin replaced the One Pound note in the British currency in 1983. Pound coins include the One Pound and Two Pound coins, and the Five Pound coin which is issued as a commemorative but is still legal tender.

The British 1996 Two Pound coin was the last Two Pound coin to be issued as a non-circulating commemorative. The coin was issued as a "specimen" and a "Proof FDC" coin. In addition to the nickel brass coins, the Proof FDC coins were also issued in silver, piedfort in silver and gold. All "Proof" coins would be issued in some sort of packaging for protection. Any coin issued in a precious metal would need to be certificated to provide a guarantee of authenticity to the purchaser.
I suggest you get a good coin book and search for your coin in there.
