Without pictures I will do my best.
1) 1c Franklin on post card: probably from the 1902 series, in production until 1908, green, Franklin facing right, fancy frame. Valued at 30 cents on cover (or post card)
2) 2c Washington, internal rev-proprietary: a revenue stamp collecting money to help pay off the debt from the civil war. Best I can do without more info.
3) 2c Washington, bank check: same as 2 above.
Both revenue stamps sound like they are probably from the first issue, 1862-1871. There are color varieties, paper varieties, and separation (perforations, straight edges, slashes)varieties that all affect the value. All of your items are best kept intact on the entire card, photo, bank check. Valuation on card/photo/check is outside of my expertise.
