Question: I began collecting stamps in high school but unfortunately put my collection on hold while I attended college. Now that I've graduated I'd like to get involved again, but I haven't been able to find any stamp shows here in San Diego. What is the best way to find them?--M.K.
Answer: The Los Angeles area has bigger and more extravagant stamp shows than San Diego, but there is the San Diego Stamp Fair, which is held frequently throughout the year at the Stardust Hotel in San Diego.
For a schedule of dates and other information on these shows, write to Edward G. Rosen Enterprises, Box 5502, Redwood City, Calif. 94063.
Q: I own 23 Pakistani stamps from 1957 to 1986, with errors. On some, the amount is printed wrong; on others there are colors that are different from the original issue. What is their present value?--A.A.
A: Pakistani errors are not the most popular items in the stamp market. "Stanley Gibbons Stamp Catalogue, Part I: British Commonwealth," lists some stamps from Pakistan with known printing errors. For common errors you might expect to get about $5 or $10 per stamp.
If the error is extremely rare (one sheet found, for example), then the value would rise considerably. Show your stamps to a dealer for a quick evaluation.
Q: I have two sets of British Red Cross Centenary Congress stamps. One set has three phosphorus bands and the others do not. Would you help me to determine their value?--F.H.
A: Issued in 1963 to honor the Red Cross Congress in Geneva that year, these British stamps were printed both with and without phosphorescent chemicals on the face of the stamps. The phosphors aid in mail sorting by electronic machines.
Your set of three values is priced at $11.75 without phosphorus, and $99.50 with phosphorus, both prices assuming mint condition.
