Nothing is wrong with your H9a. The first pump is about 15 lbs and the 8th pump is about 38lbs. It is designed this way. But it get over 400FPS (Feet Per Second) and that is fast for a pistol. Everyone says it is hard to pump.
It was manufactured in 1978

The sheridan H series in good condition is roughly worth $100
Sometime around 1980. In 1977 Benjamin bought out Sheridan and for a time they merged the names Benjamin/Sheridan.
I Think I've located the answer to your question. A short history. Benjamin air rifles and Sheridan air rifles once were separate companies. Sheridan developed the C series 20 caliber series of rifles. Benjamin bought Sheridan and continued to make the C, 20 caliber series rifles. They also made a .177 and a .22 caliber C series rifle called a Benjamin. Crosman bought out Benjamin (in 1992) and decided to continue making the C series. With the name Sheridan on the .20 cal rifle and Benjamin on the .177 & .22 cal rifle some rifles also had the Crosman name on them. ( confused enough?) Because you have asked for about a Crosman C9 I believe yours in one of the older models. It was most likely made around 1990. From 1949 to 1990 they were just called Sheridan later called C9 and CB9. But I am not positive.
The C9 was discontinued in 2012. But I think yours is much older. Sheridan had a very unusual past ( too long to go into here) I suggest you go to the CROSMAN web site and give them the serial number and ask them for information on you rifle. Call them. Crosman owns both Sheridan and the Benjamin line of airguns

During all this confusion and name changing the C9A came along. I have 4 reference bluebooks on air guns and not one of them can give me a date for the C9A, But Crosman has a web page that list manufacture dates by serial number for Benjamin and Sheridan. (See the link below) when it opens scroll down to the Sheridan dates. (the first part is all Benjamin) Hopefully you have the serial number and can match the number with a date of manufacture.

This pistol is also known as the HB17 or H17. In order to set a value I need to know the condition of the pistol. Is it in Poor, Fair, Good, Very Good or Excellent condition?
At one time Sheridan, Benjamin and Crosman were all separate companies. In the 1970's. Benjamin bought out Sheridan and took over the company. In the 1990's Crosman bought out Benjamin. Now Crosman owns all 3 companies. When Benjamin bought out Sheridan they decided to keep the C series design. So they decided to keep the Sheridan name on the .20 mm air rifle and put the Benjamin name on the .177 and .22 caliber 392 series air rifle that looks just like a Sheridan C Series. So All Sheridan C series are .20 caliber and the .177 and .22 are Benjamin's. Crosman decided that this worked well and kept the same arrangement for both models. If you go to the Crosman home page you will find (At the bottom of the page) a link to (Owners and Parts Manuals) there you will find the owners manual in the Benjamin / Sheridan section.
