No. Many colors were used on silver certificates until colors were standardized in 1928, but purple wasn't among them. You may have a blue-seal bill that's changed color from age or being exposed to some chemical.
There aren't any Federal Reserve indicators or seal on silver certificates. Silver certificates were issued directly by the government and not through the Federal Reserve system.
Please check your bill again and post a new question. A blue seal bill would be a silver certificate; the last $5 silver certificates were dated 1953 and the last silver certificates of any type were 1957-B $1 bills.
The U.S. did not print any bills of any denomination that were dated 1948, and the last $2 silver certificates were dated 1899. All $2 bills printed after that were red-seal US Notes or green-seal Federal Reserve Notes.
I cannot find a listing for any U.S. silver certificates with that date. There were $1 National Currency notes and $50 Federal Reserve notes printed that year. Please post a new question with the bill's denomination, seal color, and any specific wording. Don't assume that a blue seal represents a silver certificate because seal colors were not standardized at that time.
Yes. 1923 $1 bills were issued as both red-seal United States Notes and blue-seal silver certificates.
Orange, purple, and silver do not have any words that rhyme with them in the dictionary.
Please check your bill again and post a new, separate question. The US didn't print any bills dated 1946, and the last blue-seal $20 silver certificates were printed in 1891.
The U.S. did not print any $5 silver certificates with that date. Please check again and post a new question with the bill's seal color and what letter, if any, appears next to the date.
If you're referring to small-size bills printed in 1928 or later, there are no red-seal silver certificates. Starting that year the Treasury adopted standardized seal colors:Green = Federal Reserve NoteBlue = Silver CertificateRed = United States NoteGold = Gold CertificateBrown = National Currency NoteBecause many people aren't familiar with all of these older types they tend to assume all old bills must be silver certificates. However if you check the seal color and the banner across the bill's top front it's easy to tell the difference.The situation is more complicated for bills printed before 1928. There were no standard seal colors, so it's possible to find just about any combination of seal color and bill type.
More details are needed. Silver certificates were issued for about a century in many different denominations. Please post a new question with the bills' seal colors, dates, and what letter if any is next to the date.
The last $2 silver certificates were made in the 1890s. If you have a U.S. Note with a red seal, please post a new question with the bill's exact date and what letter, if any, is below the date.
The U.S. did not print any silver certificates with that date. Please check again and post a new question. Include the bill's seal color and whether there is a small letter right next to the date.
